Off-Road Revival does a complete rebuild of your shock. We disassemble, clean and lube all necessary parts. Includes new dust seal, oil seal, seal head o-ring, fresh Lucas Synthetic Shock Oil, nitrogen re-charge: and in several cases the bumper as well. (A bumper is not included on some models where the bumper rarely ever need replacing.) On front shock rebuilds, bottom out bumpers will be replaced on an "as needed basis", and would be an additional charge. Any additional worn, damaged or broken parts needing to be replaced beyond what is previously listed, would be an additional charge. We can also re-valve and re-spring your shocks for your specific weight, riding type, and skill level.
