The Shocker clamp-on side mount bracket kit is great for mounting a trailer jack on a trailer A-frame. It is the ultimate no-drill, no-weld solution for owners of boat, flatbed, and utility trailers who demand heavy-duty performance without compromising their trailer’s structural integrity. Available for round or square trailer jacks. Engineered to fit jacks with a 2-1/4″ outer tube and a 2″ inner tube, both the SH-7020 round bracket and SH-7030 square bracket are rated for a maximum tongue weight (supported vertical load) of 5,000 lb. This is a jack-bracket support rating, not a trailer towing-weight rating. Do not exceed the ratings of the jack, frame or any other supporting component. By utilizing a sophisticated clamp-on system rather than permanent welding, you avoid the risk of heat-weakened metal or rust-prone drill holes. This design ensures a flush, rock-solid fit against the 2-1/4″ jack stem, preventing the “walking” or shifting often found with inferior mounts, while allowing the 2″ inner telescoping stem to operate smoothly under heavy loads.

The true standout feature of this kit is its unmatched adjustability and versatility. Designed to fit frame rails from 4″ to 8″ tall, the bracket can be positioned exactly where you need it for optimal clearance and leverage. Whether you choose the Round Option for its universal compatibility or the Square Option for its superior resistance to twisting and lateral stress, you gain the freedom to mount your jack on the inside or outside of the frame. Each kit includes carriage bolts, hex bolts, flat washers, lock washers and nuts for installation on standard 2″ thick frames. Installation requires a 9/16-inch wrench and a ratchet with a 9/16-inch socket, as listed in the REV A installation manual. It’s a customizable, high-capacity mounting system that grows with your needs, allowing you to reposition or swap your jack without ever touching a drill or a torch.
