Simply the Best RV Bumper-Mounted Hitch on the Market Today

Why settle for an outdated, inferior 4-inch RV bumper-mounted receiver hitch, many of which can actually damage your bumper, when you can have a computer-designed, laser-cut, clamping hitch? With a ShakeStopper® Clamping Hitch, you can transport the investment you’ve made in your e-bikes, bike rack, or cargo carrier in safety, style, and security. The bumper-mounted ShakeStopper® Clamping Hitch features dual pressure plates and heavy duty nut/bolt combo for securely clamping your bike rack or cargo carrier in place.

Most hitch receivers on the market today are made from welded steel tubing that leaves a 1/16” gap around your bike rack’s mounting bar. To compensate for this sloppy fit, small diameter retention bolts are used to try and reduce movement, instead that damaging your accessory’s mounting bar. Our unique dual pressure plates distribute the clamping force, reducing the risk of damage to your accessory.

Lastly, our patent-pending design has no load-bearing welds or bolts, eliminating these points-of-failure, so you can travel with the peace-of-mind that comes from knowing your cargo will arrive at your destination when you do.
