Your RV bumper may look strong, but without support, it's vulnerable to damage from the weight and torque of cargo carriers, bike racks, and rough road conditions.The Quick Products QP-SBSBU Standard RV Bumper Support Brackets solve that problem by transferring load forces from the bumper to the RV's structural frame—where they belong.Compatible with 4" x 4" square bumpers and frame styles 6" or taller (I-beam, tube, or channel), these rugged steel brackets cradle the bumper and prevent cracking, tearing, or weld failures. Once installed, your bumper's load capacity increases to 400 lbs, making it safe for carrying hitch-mounted accessories over long distances and uneven terrain.Perfect for travel trailers and fifth wheels, these brackets are a smart upgrade for anyone using rear bumper accessories. Installation is straightforward but requires drilling into the RV frame for maximum reinforcement.
