The Bump Stop In high-power bikes the O.E. chain tensioner can over tension the primary chain during hard acceleration. The Bump Stop eliminates over tension from the O.E. chain adjuster found on ‘07 to Present Big Twin (Also ‘06 Dyna). The Bump Stop provides a physical impediment to the ratchet function of tensioner while the spring mechanism remains in place for proper tensioning. Made from high quality steel and black oxide coated for corrosion resistance. Machined grooves help to grind straight to make fine adjustments to the chain tension.
