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

Why settle for an outdated, inferior 4-inch RV bumper-mounted receiver hitch when you can have a computer-designed, laser-cut, modern hitch for roughly the same price? With a ShakeStopper® Clamping Hitch, you can transport the investment you’ve made in your bikes/ebikes, bike rack, or cargo carrier in safety, style, and security. The ShakeStopper™ bumper-mounted clamping hitch features a pressure plate 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 steel tubing that leaves a 1/16” gap around your bike rack’s mounting bar and small diameter retention bolts that damage your accessory’s mounting bar. Our unique pressure plate distributes 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.
