RockJock 2 in. Rear Bump Stops for JT Gladiators mount to the vehicle's factory rear axle housing bump stop pads and are designed to be used in conjunction with all of the stock JT upper bump stop hardware in lifted applications, guaranteeing proper bump stop contact in high articulation situations. The vehicle's factory yellow jounce bumpers are retained to provide a factory feel when the bump stops make contact. Finish is semi-gloss black powder coat and zinc plating on the hardware.
