I've called two Bilstein dealers and no return phone calls yet(3 days) with the info. KYB's are decent but I've run them in two separate situations; once as a lesser expensive solution to OME which I changed out later and was happy with the change and the next was a similar situation. I bought a FJ on CL and flew to pick it up but the shocks were so shot it was dangerous to drive so the only option was KYB's. I drove the 1700 miles "home" on the trip and ordered my lift with Bilsteins. Replacing both the springs and shocks at the same time may not be quite fair as a true comparison but I was much happier with the dampening and rebound on the 5100's that I installed over the KYB's.

I'm looking for that series per the personal experience but if there isn't one that's valved correctly in the lengths that I need then I'll check out the KYB's if OME's are still indefinite.
