Zone Offroad Products Bump Stop Extensions ZONJ5304

This bump stop extension kit includes a pair extensions that attach with a 3/8" bolt to create a universal mounting platform very common on Jeeps as well as many other vehicles. Bump stop extensions limit a tire's upward travel into the fender well, limiting spring travel to prevent failure and fatigue by keeping the spring from being over-compressed on lifted vehicles - especially those with larger-than-stock tires.
