Zone Offroad offers this bump stop extension kit that includes a pair of 2" tall by 3" diameter extensions. These attach by simply with a 3/8" bolt for a universal mounting platform very common to many vehicles. If you have installed large tires or a lift and have not thought about extending your bump stops, think about this: bump stop extensions limit spring travel to prevent spring failure and fatigue by keeping the spring from being over-compressed. In addition, bump stop extensions also prevent rubbing by limiting the tire's upward travel into the fender well. Zone Offroad offers various sizes to fit the specific needs of your application.
