Stop destroying your trailer and cargo.
Every bump, pothole, and expansion joint sends a violent jolt through your trailer frame, damaging cargo and wearing out your truck. Shocker Air Ride Hitches absorb that punishment at the coupling, before it reaches your trailer.
The Shocker clamp-on side mount bracket kit is great for mounting a square 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. Engineered to fit square trailer jacks with a 2-1/4" outer tube and a 2" inner tube, this kit is rated for a massive 5,000 lbs maximum towing weight. 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. With superior resistance to twisting and lateral stress, you gain the freedom to mount your jack on the inside or outside of the frame. Each square trailer jack mount kit comes fully loaded with high-strength hardware, including stainless steel countersink bolts and a hex wrench, to ensure a professional, secure installation on standard 2" thick frames. 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.
