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).

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.

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!
