When installing our products, namely coilover kits, onto your car, you will probably end up looking through the Installation/Instruction Manual.
In the Installation/Instruction Manual you will find a few warnings regarding the use of Impact Tools.
The general warning will be along the lines of: Don’t use them, unless it is absolutely necessary.

Here we have a prime example of what can possibly go wrong if an impact tool is used incorrectly.

The Piston Rod has come out of the Damper. Unfortunately it is not as simple as pushing the Piston Rod back into the damper. As you’ll see in this next picture, all of the internals have come apart.

This will require a basic overhaul just to even get the damper back into one piece. If the damper comes apart slowly and eventually decides to give out while you are driving, a lot of internal damage will ensue.

Another thing to look out for when assembling and installing coilover kits is to never hold the Piston Rod with a set of pliers.
This sort of damage is evident in this damper’s Piston Rod by the dark ring and scratches going in a circle around the Rod.

These scratches will cause damage to the oil seal and ultimately the premature failure of the damper.
