one option, before you order the race tech seal head which is a great fix, pull your shock apart, disassemble the shock rod, pull off the seal head, remove and replace the o ring in the seal head. I have done that several times on hard to find shocks, the o ring is the oil pressure seal. Many times this is a long term fix. If the shock is really been used.........say 5000 plus miles, then its is important to have the new bushing and the dirt seals brand new, the race tech seal head then is the best fix.
