These 3D printed rubber bump-stops are designed to replace the 3rd Gen 4Runner rear hatch bump-stops. They are printed from a high quality TPU and are designed to be 3mm shorter than the factory bump stops to accommodate brackets that utilize this mounting area. This fixes a common issue where the rear hatch is stiff or hard to close after adding a rear facing CB antenna mount or a light bracket. The brackets have washers press fit into each hole to provide for better load distribution similar to the factory mounts.
