Sandblaster, Race Tech refurbished shock body, shaft, and reservoir-I sent them about 2.5 shocks worth of parts in order to be able to build one good one. New gold valve / re-valve, rebound separator, and rebuild with new seals, head, oil, bushings, etc. New spring (5.4 kg/mm). They don't make a 275mm length spring in the correct ID anymore so they provide an aluminum spacer.
