When driving on rocky terrain, the factory-installed bump stops on your vehicle find it hard to withstand the extra amount of force placed on them. However, with the RSO Suspension Hydraulic 2.0 Bump Shocks with 2.5-inch stroke were designed to withstand those forces. They allow you to safely use all of your vehicle's effective suspension travel without damage to OEM or aftermarket shocks and preventing damage to your undercarriage. Factory rubber bump stops installed by manufacturers, are not designed for repeated use unlike the RSO Suspension hydraulic bump shocks which are completely rebuildable and serviceable for quality performance throughout your vehicle’s life.
