Replace your rubber OE front bump stops with these red polyurethane ones from Rugged Ridge. There has been an ongoing debate about rubber vs. polyurethane as to what is better, It truly depends on how you are using your Jeep. In most cases polyurethane outperforms its rubber counterparts in replacement of bushings and mounts. The products will last longer standing up to road debris, chemicals, oils, compression, and load. They will perform better by removing additional sloppiness in suspension performance due to worn, damaged, or missing bushings. It is however, a little stiffer than rubber.
