As proof that Coilovers just like normal shocks need regular maintenance and wear out, I thought I'd post this.

In the process of prepping my DMS 50s to send them out to be "rebuilt", I found that at least two of them will be MAJOR rebuilds.(#3s)

In case you didn't know, there are usually 3 levels of coilover rebuild.

1. Dismantle housings, clean, relube and put back together. (For monotubes mostly)

2. #1 + replace the bushings between the two cylinders. (For Invertedes mostly)

3. #2 + dismantle the damper itself. service valves, replace fluid, repressurize, etc.

In about 5K track miles and 25K street miles, both of my rear dampers are bad.

One of them is leaking like a sieve out of the damper shaft seal and into the lower housing. The other has at minimum lost pressurization.

The fronts appear OK and will likely be OK with #2 but will let the professionals check them out.

So for those of you who have coilovers and especially if you track them, I would suggest you get them checked out every year...
