Give your Jeep the ultimate off-road damping with Rough Country’s Threaded Hydraulic Bump Stops. Your Jeep’s factory bump stops simply aren’t equipped to handle the intense force that can be applied in aggressive off-road scenarios. This pair of high-end, hydraulic bump stops feature a mixture of advanced suspension fluid and compressed Nitrogen to control the final inches of suspension travel providing a cushioned response during off-road travel. An Internal Floating Piston (IFP) in the shaft separates the oil and nitrogen to prevent cavitation.Rebuildable
