Had the fronts done. Basically one was bad, somehow all the nitro charge leaked out (and it was only a year old), had the other one done just so they would be the same. The valves were replaced, seals, and the shock fluid and nitro charge. I asked them to use the heaviest shock fluid they could to stiffen them a little more than stock, and it seems like they might be a little. All in all, they turned out great! They even did a nice job of cleaning the shock. The one thing is the original top cap gets damaged when removed, since the add a schrader valve to recharge. all parts are returned, so I simply put it back on, although it sits a little higher up, and resealed it with silicone. Its awesome if you like the feel of the OE shocks. He can also retune them if you wish. I plan on doing the rears just to make them a little stiffer and cause they are the orignals (although not blown yet).
Cost was about $300 for both plus shipping.
I highly recommend Bruce's Suspensions, tell him I sent you (Mike Skurich).
He will know exactly what to do.
