The 4SQUARE™ SafetyStruts™ Ultralight Aluminum 4-Inch RV Replacement Bumper Kit is designed to replace your RV's existing square steel bumper. Many RVers experience partial or complete bumper failure due to overloading of the stock bumper with cargo accessories such as bike racks and cargo trays. Once the stock bumpers start to break free of the frame, there's not much that can be done other than to replace them. Our kit allows people to quickly and easily replace their stock steel bumper with a superior aluminum one; no welding and no painting required. Plus, the innovative design of our aluminum replacement bumper mounting brackets allows you to carry up to 500 pound-feet of cargo (i.e., 500 pounds supported one foot out from bumper), well in excess of the weight ratings for stock bumpers.
Upgrade from your old, rusty 4-inch square tube bumper to this stylish, ultralight all-aluminum cargo bumper. Our patent-pending design weighs only 21 pounds (bumper, brackets, and fasteners) and installs easily on most vehicle frames using common tools. Adding this bumper to your RV provides you not only rust-free storage for your sewer hose, but also a rigid "backbone" for the quick, safe, and strong mounting of 4-inch bumper-mounted hitches and accessories such as those shown at bottom of page. Make the most of your journeys by taking along more of the gear that you need and enjoy the peace of mind that comes with knowing it will arrive safely at your destination.
