Tesla Model 3 Suspension Arriving Soon!

Posted on by

So we’re a bit late to the party. But better late than never, I suppose. We’ve probably said this many times before.

As Electric Vehicles continue to grow in popularity, and with many nations looking to reduce carbon emissions or become carbon-neutral, it was only a matter of time for the Electric Vehicle market to take off. And it really has taken off.

That’s a great opportunity for aftermarket manufacturers such as TEIN. People may need to rely on their Electric Vehicle strictly for commuting. However, that doesn’t mean they cannot enjoy their car for what it offers at face value. As always, where there’s a vehicle, the performance market is not far behind, and everyone wants that extra bit of performance, whether it be in power or handling, or just to simply have something different or unique.

As many of you have seen by now, the modern Electric Vehicle, namely the Teslas, are quite quick in acceleration. The manufacturer has done pretty well in setting their cars up. But let’s be honest, they’re catering to a global market. You can’t appease each and every person with a “run-of-the-mill” Tesla, regardless of which model Tesla it is.

So, we’re coming out with some performance suspension kits, starting with the Model 3, and soon the Model Y.

For the Model 3, both rear-wheel drive and all-wheel drive models, we’re making our S.TECH lowering springs, ENDURAPRO and ENDURAPRO PLUS shock absorbers, as well as our FLEX Z coilover kits.

The S.TECH lowering springs will provide a nice lowered ride height without being too aggressive. These will pair well with OEM shocks and struts, but for sure our ENDURAPRO or ENDURAPRO PLUS shocks will be a better pairing.

ENDURAPRO and ENDURAPRO PLUS (16-click damping adjustable) shocks are true performance replacement shocks. Damper tuning is optimized to reduce body roll and provide better response to fast inputs. But beyond the tuning, the internal Hydraulic Bump Stopper (HBS) in each shock absorber provide increased comfort and safety by reducing a typical shock absorber’s tendency under full compression (bottoming out) to oscillate. This feature also increases vehicle stability in emergency maneuvers, especially in vehicles with added weight. Also, although designed to be a direct OE fitment, we incorporate a lot of features typical of our coilover kits- larger diameter damper bodies (increased damper oil capacity, larger diameter piston rods, and use of ultra high-strength steel in its construction.

Our FLEX Z coilovers, on the other hand, are for consumers who need much more than what our lowering springs and performance shocks can offer. FLEX Z coilovers provided full-length adjustability (separate spring preload and ride height adjustment), 16-way damping adjustment, upper mounts for front and rear dampers, high-rate springs, and valved to provide greater handling performance without compromising ride feel. For sure, much more aggressive for street, but not at the ride quality penalty typically associated with aftermarket coilover kits. Lastly, our FLEX Z coilovers are compatible with our optional Electronic Damping Force Controllers (EDFC)- ACTIVE and ACTIVE PRO, giving you the added benefit of damping adjustment from the driver’s seat. No need to have to manually set your damping by hand, and you can also save up to 10 different presets. However in Active mode, you can have damping that changes based on driving speeds or g-force load. This EDFC setup makes the FLEX Z a true adaptive suspension setup.

TEIN Hydraulic Bump Stopper Technology

Posted on by

Lately one of our greatest developments to hit the mainstream in TEIN suspension kits is our Hydraulic Bump Stopper (H.B.S.) system.

This technology isn’t anything new. However, the current derivative is a much more affordable design, and has now made its way into coilovers like our FLEX A and FLEX AVS kits, and now our ENDURAPRO & ENDURAPRO PLUS shock absorber lines.

Why are we creating so much buzz about this system? Mainly because a comparable Hydraulic Bump Stop system isn’t typically found in passenger vehicles, outside of trucks where you’d have to opt for something like an externally mounted bump kit.

Even our current Hydraulic Bump Stopper system used in our FLEX A, FLEX AVS, & EnduraPro/EnduraPro Plus shock absorbers differs from systems used in rally suspension, which are typically much more expensive units and require rebuild. Our current system is more affordable to make and doesn’t require servicing (FLEX A and FLEX AVS dampers are rebuildable, but the H.B.S. system doesn’t need to be rebuilt, per se).

Still, all this hype we’re making about a Hydraulic Bump Stopper doesn’t mean much if you don’t know what it does. So, picture this: You’re in a fully loaded vehicle (max occupancy) and have the trunk fully loaded. Already you can picture the suspension starting to sag. Then, while driving, you hit a big speed bump. On any normal suspension, chances are you’re hitting the bump stops, which will do a great job of preventing the shocks from bottoming out. However, the consequence of hitting the bump stop is a harsh impact and resulting bouncy or wallowing feeling.

Now, a Hydraulic Bump Stopper eliminates this bouncy/wallowing feeling. It does so by creating more damping force towards the end of the damper stroke.

Typically our dampers are valved to offer a digressive feel, meaning that as piston speed (of the shock absorber) increases, it will only increase damping force to a certain extent, then it actually does not increase in force if piston speed is even higher. That is typically fine, but when this high piston speed is towards the end of the shock’s stroke length, it will have that harsh feeling (remember that bump stop?) we’re mentioning about.

Honestly, a damper with progressive or linear rate damping can still hit a bump stop and cause that harsh feeling.

But why does creating more damping force with the Hydraulic Bump Stopper help? Essentially it’s slowing down the piston of the damper. It gradually builds up this damping force so that the end result is a smoother absorption of force, while letting the damper rebound normally without oscillation.

When you see Stadium Trucks or Baja Trucks take on a massive jump, what you see on its landing is actually quite impressive. The suspension fully compresses, but as the suspension extends again, it’s nice and smooth. No crazy up and down oscillation. That’s what our H.B.S. system does, but for a smaller scale (shorter stroke length than Stadium or Baja Trucks, obviously).

Or, another example: Using lowering springs on OEM or replacement shock absorbers. While this setup is common place, and most work relatively well, some lowering springs might be too low of a ride height or too stiff a spring rate for the OEM valved shocks. A premium replacement like our EnduraPro line is a better match. Valved to offer a beneficial increase in performance, the added Hydraulic Bump Stopper is a nice addition because of the lowered ride height with lowering springs.

While our EnduraPro/EnduraPro Plus shock absorber line is a match in terms of overall length (compared to OEM), they offer larger internal capacity and more damping oil, and improved damping characteristics. So from a performance standpoint, these are a great upgrade for your lowering spring. Again, these include our H.B.S. system, and when lowering a car using OEM/standard replacement shocks, reducing that stroke length can mean exacerbated issues with ride quality and more chances of hitting that dreaded stock bump stop. You’d end up with similar ride issues in a fully loaded vehicle. Now we can resolve this potential issue by using the increased damping force the H.B.S. system creates further down the shock absorber’s stroke length!

It really is an ingenious system, and one that we’re glad to bring into mass-production. The fact that we can adapt this product into our replacement shock absorber line means that this feature is available to all consumers, whether their budget allows for just our premium shock absorber replacements only, or for those looking for greater handling performance (like our FLEX A or FLEX AVS coilover kit). We’re hoping to add this to many more of our products in the near future!

More Applications of ENDURAPRO/ENDURAPRO PLUS Available!

Posted on by

We’re well on our way with our new ENDURAPRO & ENDURAPRO PLUS premium shock absorber line, launching new vehicle applications nearly every month!

To simplify what we have available, I’m adding our New Product Guides previously sent to our authorized dealers and distributors:

TEIN Endura Pro Plus Shock Absorbers

Posted on by

This is probably the single most anticipated product from TEIN, for me at least. Why? Probably because I’m reaching a point in my life where I want a simple suspension setup that will work well, and I can do away with a bunch of features I will not really use often. In other words, I’m getting old and lazy.

The TEIN group has been discussing this new line, which is a premium shock absorber, for probably the past five years (to my knowledge). We’ve wanted to get into the replacement shock absorber line for some time now, but we wanted something that had an appreciable difference to the well-known aftermarket shock absorbers already on the market.

So, after all these years and years of discussion and product development, we now have our Endura Pro and Endura Pro Plus shock absorber line.

These shock absorbers are completely compatible with OEM vehicles. As stated, it is a replacement shock absorber. HOWEVER, it is far from a simple replacement. We’ve gone an extra step in making them a high performance shock absorber. In saying that, this product is not the same type of suspension as our existing line of coilovers, which in many cases offer a firmer ride and drastically reduced vehicle body motion (sway, squat, dive). The Endura Pro/Endura Pro Plus line does offer a very comfortable ride quality, but internally it is much different than a standard twin-tube shock absorber you’ll find as an OEM shock.

For starters, we actually have increased the internal capacity of the shock absorbers. In most cases, our Endura Pro/Endura Pro Plus shock absorbers are the same length as an OEM shock (a few applications use a slightly shorter damper body), but we also use larger diameter damper bodies, thus the internal volume is greater. In doing so, we’ve increased damper oil capacity over a standard shock absorber for the same vehicle application. That translates to better endurance (long-term driving) and increased longevity. It also allows us to use a larger than OEM piston valve which provides a greater damping force range.

For strut type applications, we use thicker piston rods (22mm dia.) able to withstand greater lateral loading that struts are subjected to.

Since we use the same high-strength steel as used in our coilover kits, it allows us to reinforce areas of the damper, like the lower brackets on strut type suspensions, or the spring seat or sway bar bracket, without a large penalty in weight. In fact, for some applications the Endura Pro shock absorber is actually lighter than OEM!

Depending on the vehicle application, we will include necessary hardware to make the installation easier, such as collars, bump stoppers/washers, dust boot, bump stop, etc.

OEM shock (bottom) has a crimped collar, making removal of the dust boot, bump stop, and washer impossible. Endura Pro will include new hardware if necessary.

One new feature recently only applied to the TEIN FLEX A coilover kit has now made its way into every Endura Pro/Endura Pro Plus shock absorber- our Hydraulic Bump Stop. With the aforementioned FLEX A line, the only other TEIN product to incorporate a Hydraulic Bump Stop is our Gr.N rally coilovers. The off-road crowd probably knows a fair deal about how a hydraulic bump stop works- it creates higher damping force on compression to prevent the suspension from bottoming out completely, then allows the suspension to settle in a very controlled manner on rebound. What you end up with is a reduction in suspension oscillation (excessive up and down movement, or “porpoising”). Never before has a replacement shock absorber ever had such a feature.

The Endura Pro Plus line, specifically, has 16-way damping adjustment, similar to our other damping force adjustable coilover kits like STREET ADVANCE Z, FLEX Z, MONO SPORT, etc. This gives the end user the ability to set their suspension to their preferences depending on their driving conditions. As an added bonus to having this damping adjustment, this technically makes the Endura Pro Plus shock absorbers EDFC series compatible! With EDFC, now you can control the shock absorber damping settings directly from the driver’s seat. Opt for the EDFC ACTIVE or EDFC ACTIVE PRO series, and you’ll get adaptive damping force control based on speed or g-force loading! EDFC is a universal application for our 16-way adjustable TEIN dampers, so any car can use this setup (some vehicles may require modifications or adapters to make the EDFC Motors fit properly)!

Lastly, the Endura Pro/Endura Pro Plus line adopts our new fully sealed structure in helping keep manufacturing costs (and MSRP) down. These shock absorbers will be available for sale individually, but we’ll also be offering them as a complete set with TEIN S.TECH lowering springs!

So again, this new Endura Pro/Endura Pro Plus line is far from a simple replacement shock absorber, and now I can say I know that personally.

After constant nagging to my boss, I wanted to see if we would be making some for the GD3 Honda Fit (2007-2008). Since I’ve taken ownership of my dad’s Fit, I’ve grown to love driving it. It’s by no means a fast car (quite the opposite, actually. I’ll just call it “brisk”), but it is small, lightweight for its size, and kind of fun to drive in a spirited manner. And it’s a practical car for me now that I have a small family of my own. The Fit also saves me from wasting gas in my truck driving solo to and from work, so it’s now my daily driver.

Now, with 80,000 miles, which is relatively low for this year vehicle, I can feel the suspension is not as it was when it was newer. Of course that can be from a number of things, but the shock absorbers are a pretty high wear and tear item in the suspension, so that felt like the cause. After removal of the shocks and compressing them by hand, there was still at least some nitrogen charge in all the shocks, but maybe not enough to really provide good rebound force.

Anyway, to get to the point, I finally got a set of Endura Pro Plus shock absorbers for the Fit!

 

DISCLOSURE– The Endura Pro Plus shock absorbers I’m using are designed for the Japanese market GD3 Honda Fit, which is not a direct fitment for the front.

 

This required some modification to the knuckle brackets by boring out the bolt holes to 14mm. Still, this isn’t a direct fitment even after this modification. The struts are the same length as the US Honda Fit OEM strut, however the spring seat and sway bar bracket are 20mm higher than the OEM strut (fortunately this poses no clearance issues). So, this actually does translate into a slightly higher front ride height. For my Fit, it was approximately 12mm higher than stock ride height in the front.

*Endura Pro Plus Strut (bottom) had bolt holes in lower bracket bored to fit USDM GD3 Honda Fit.

The rear dampers are a direct fit, so no problems there.

Clearance at the bottom is very close to the axle beam, due to the larger diameter body of Endura Pro/Endura Pro Plus shock absorber. Fortunately no contact with the beam, even at full droop.

With the shock absorbers set at 8 clicks (middle) front and rear, the ride quality felt very much as I remembered the car feeling like when new. That was ten years ago though, so I really only have a memory to go off of. One of my co-workers said that the shocks set to 16 clicks (softest) was actually an improvement over the worn OEM dampers. At 0 clicks (stiffest) it is actually a noticeably firm ride quality, but far from being jarring (the Fit uses soft springs). I found that a 12 click front and 10 click rear was more to my preference. So I drove on that for about a week, until one of the guys here (Gonzo, aka Cpt. Slammo, aka Monster Tuck) kept telling me “it needs to be lower”…. ughhh.

I actually wanted to lower the car a little anyway. Go figure. I mean that’s really what TEIN suspension is known for doing, so it’s only natural to want to use the products I help sell. So, I bought a set of our S.TECH lowering springs for the Fit (part # SKB36-AUB00). Knowing that the front struts are now a bit higher than the OEM strut, I thought the car would look a little funny with a slightly raised front end. But, to my surprise the ride height actually has a relatively even drop front and rear (referring to tire-fender gap)! The front actually dropped a little over 2″ front and 1.2″ rear (we spec S.TECH’s for the GD3 fit at -1.8″ front and -1.2″ rear). So even with the Endura Pro Plus front struts having higher spring seat position than OEM, it’s nearly about the same ride height as our test data. That difference can be due to the strut mounts (being mostly rubber) starting to sag.

As for ride quality, now it feels more in line with how one of our coilover kits feel, like a STREET ADVANCE Z for example. Not incredibly stiff, but nice and sporty with good compliance for my daily commute. The extra flexibility in having damping adjustability is a worthwhile upgrade, especially if you’re considering using lowering springs with new shock absorbers.

All in all, I’d say this is probably the happiest I’ve been with driving the Fit. The lowering springs really helped reduce the body motions (the Fit has a pretty tall roof line). The reduction in body sway is a dramatic improvement! I’ve found a damping setting on the Endura Pro Plus’s that works really well with the S.TECH’s.

In general, as a replacement shock absorber, the Endura Pro line is a great improvement over the factory suspension. Adding the adjustability I get with the Endura Pro Plus shocks gives me a chance to find a ride quality I prefer!

New Suspension Developments at TEIN

Posted on by

Always working to be innovative when it comes to suspension, we’re constantly testing and developing new components in search of greater performance, longevity, and overall quality to our product lines.

We’ve possibly mentioned before that we had always planned to produce our own line of premium shock absorbers, designed to work with OEM springs or our lowering springs. In fact, if you have been to the SEMA show, you’ll know that we displayed a prototype product called “Premier”. We’ve noticed a great demand for such “replacement shocks and struts”.  However, there are already a number of manufacturers making replacement shock absorbers and struts. We don’t simply want to be another addition to all these manufacturers.

So, while considering what type of shocks we’d produce, we started to think about how we can just simply make a premium shock that has longer life span than other replacement shocks. After all, a reliable suspension is something we pride ourselves in creating (along with great value). Fortunately nearly all of our technologies in shock manufacturing high performance suspension can be applied to our premium line of shock absorbers.

Not being enough to set ourselves apart from other companies, we needed innovation. So, after much deliberation, we’re adding our new Hydraulic Bump Stop (H.B.S.) to this premium shock line, and not to just a few applications. H.B.S. will be added to all of our premium shock absorber applications.

Structurally, these new shock absorbers will also benefit from increased rigidity and thicker than O.E. brackets/mounting points on the shock body. This contributes to greater steering feel for strut type applications and safety for the overall design. Internally the damper volume is much greater, allowing for increased damper oil capacity which, in turn, allows for greater long-term performance and reduced fade in damping force over extended usage. And, due to our use of high-strength steel for its construction, we can maintain a product with minimal to no increase in weight compared to O.E.

Since introducing this future new product at SEMA as our “Premier” line, our new premium shock absorber line is now the Endura PRO and Endura PRO Plus. Endura PRO will have a set damping rate per application, while Endura PRO Plus will have 16-way adjustable damping much like our STREET ADVANCE Z, FLEX Z, & MONO SPORT line. One exciting fact about the Endura PRO Plus is that some applications (depending on fitment limitations of our EDFC motor) will be compatible with our EDFC series controllers!

As mentioned, these premium shock absorbers will be designed to work with OE springs (and with TEIN lowering springs, for that matter). While being designed around OEM shock absorber dimensions, valving will be optimized for greater performance. Also, since this line is aimed towards customers needing a better OEM type replacement, this product line will be applicable to a wide variety of vehicles (compact, sport car, full-size sedan, minivans, trucks, & SUV).

As with all TEIN suspension, we will include a 1-year warranty against manufacturer’s defects. But, best of all is our starting price of $105 per shock for Endura PRO and $130 per shock for Endura PRO Plus, making these an affordable upgrade!!

We’re looking forward to this new addition to the TEIN suspension lineup, and we hope you are too!

 

TEIN Replacement Single Dampers

Posted on by

As many of our customers are already aware, we’re able to sell single dampers as replacements. While not as cost-effective as rebuilding your dampers, it is a better time-saving method of getting your vehicle back on the road.  We know that some customers have heard from auto parts stores (probably non-authorized TEIN dealers) that TEIN will only sell complete kits. That isn’t true.

We’ve heard from customers wanting their dampers serviced by us, but concerned about the 2-2.5 week turnaround time. We know that for some customers, they only have one car to use. Being without a car for a 2.5 week minimum can cause havoc to their daily routine. This is why we are able to sell single dampers.

This same service will apply to the upcoming “Z” line of dampers, such as our STREET FLEX Z, STREET ADVANCE Z, & STREET BASIS Z coilover kits. Since they are all fully sealed, non-rebuildable units, it will be much easier to just replace the bare damper (pictured below, middle).

flz_image3_en

Mind you, these are not merely damper inserts/cartridges like some other suspension manufacturers use. We mean the actual bare damper- no spring, no upper mount (FLEX Z), no lower bracket (FLEX Z). What’s the difference between an actual damper and a damper insert?

Our dampers are application-specific, meaning that each damper is made specifically for one vehicle model. Of course, there are some vehicles that share similar platforms where we can sell a single coilover kit part number (ex. 1999-2003 Acura TL = 1998-2002 Honda Accord).  In other words, we’re not simply using one design of shock absorber insert and placing them into damper bodies of various lengths just so we can say “Application-Specific”. Each coilover kit has carefully selected spring rates and dampers are valved to match (yes, we actually test each vehicle application before deciding spring rates and damper valving). That means that the internal components of the dampers, such as piston shaft, inner tube (for twin-tube dampers), and a few other components, have to be of a specific length for a given design. It is a timely and costly process, but it makes more sense to do it right. To be honest, we’re not too sure how well damper inserts work, especially if different vehicles require different damper valving and stroke length. It really doesn’t make a lot of sense.

damper and insert

You can see how a damper insert is put into an existing shell case.

Another problem with damper inserts/cartridges is their limited capacity. Because their overall dimensions are smaller than the shell case they’re being put into, that means less volume for damper oil.

For a performance damper, this limited oil capacity means susceptibility to damper fade and decreased damping force under extended use. That is why we make every coilover application to exacting dimensions for their intended vehicle. Unless it is an absolutely practical application, TEIN dampers will never use cartridges, ever!

Back on topic, this single damper replacement service is available for each and every one of our products, including the upcoming “Z” line, but will be much more affordable compared to the current rebuildable dampers.

For discontinued TEIN items or dampers we no longer have inventory of, we can remanufacture single dampers through TEIN Japan. The only problem is that customers may have to face extended downtime since the remanufactured dampers are made to order.

Our goal is to decrease a customer’s downtime on vehicle repairs. For us, this makes a lot of sense to be able to provide such service.

If you are having problems ordering a single replacement damper, please give us a call at 562-861-9161. We’re glad to assist you in getting your car back on the road!
