Fits 1987-95 Wrangler YJ. Wranglers have rubber body mounts that help isolate road noises, chassis flex and vibrations from reaching the driver. We have found these rubber mounts contribute to the rust formation on top of the steel frame to body mount. Once the rust permeates the top of the mount, it remains hidden until the major damage is done. Our frame mounts are 11 gauge steel, just like the factory, and fit as direct replacements. Available in set of 6 only.
