Shock bushings wear and need to periodically be replaced. It's a fact of life. Without the proper tools, though, the bushings can be pretty difficult to remove without risking damage to the shock itself. The 1701/5 Bushing Extractor Set is designed to make the job easy. It's compatible with 12mm and 12.7mm bushings, and when combined with a bench vise makes bushing removal possible in seconds.
