Our 6th Gen Bronco Rear Shock Skids were designed to protect the rear shocks from damage on the trail. The lower shock bolts lower links and link mounts are susceptible to damage from striking large rocks or other obstacles when driving off-road. Our Shock Guards shield these components from contact with objects passing beneath your Bronco. These skids are located on the lowest part of the rear axle which helps you to slide right off of obstacles beneath you. Both the shock and link mount skids are a single piece rather than separate skids and tying them together improves their strength. These will work with most aftermarket shocks. However shocks with piggyback reservoirs that are locked on the bottom will not fit. These will also work with most lift kits and aftermarket links using Johnny Joints and Heim connections.
