BulletProof Hitches Heavy Duty Road Suppressor Flat Plate to Flat Plate Mount

The BulletProof Hitches Heavy Duty Road Suppressor is a flat-plate-to-flat-plate vibration-damping coupler mount rated for up to 22,000 lb maximum towing capacity, designed to reduce trailer bounce and road shock between any tow vehicle and any trailer equipped with a front flat plate mount. Patented polyurethane bushings isolate and dissipate movement energy at the hitch connection point, and the mount ships with all hardware needed for installation.

Smoother Ride Through the Hitch Connection

The polyurethane bushing system in the Road Suppressor works at the point where trailer movement transfers into the hitch, the source of most towing vibration. By absorbing that energy before it reaches the tow vehicle frame, the mount reduces the repetitive shock that fatigues drivers on long hauls and rattles cargo loose over time. The reduction reaches up to 90% smoother ride compared to a rigid flat-plate connection.

Protection for Cargo, Tires, and Trailer Structure

Continuous vibration through a rigid hitch connection stresses trailer welds, accelerates tire wear on both the tow vehicle and trailer, and works cargo loose from tie-downs. The Road Suppressor's bushing design reduces that cyclic stress, which matters most on long highway runs or rough secondary roads where vibration accumulates over hours rather than seconds.

Overload Resilience and Sway Control Compatibility

The Road Suppressor is built to handle accidental overload situations without damage to the bushing system, so a single overweight load does not degrade its vibration-suppression performance going forward. The mount is also compatible with sway control systems. It is not recommended for use with weight distribution systems.

Who This Is For and Isn't

The Road Suppressor suits towers who run flat-plate hitch systems and want to reduce vibration, trailer bounce, and long-haul fatigue, particularly those pulling trailers on extended highway trips or rough secondary roads where cumulative road shock is a real concern. It is compatible with sway control systems.

The Road Suppressor requires a flat plate mount on the trailer's front coupler; it does not fit trailers with ball coupler or pintle hook connections. It is not recommended for use with weight distribution systems.

Common Questions

Does the Road Suppressor work with my existing hitch?

The BulletProof Hitches Road Suppressor is designed to work with any hitch that accepts a flat plate mount, not only BulletProof Hitches products. As long as both the hitch and the trailer's front coupler use flat plate mounting, the Road Suppressor installs between them using the included hardware.

Can I use the Road Suppressor with a weight distribution system?

The Road Suppressor is not recommended for use with weight distribution systems. It is compatible with sway control systems. If your towing setup includes a weight distribution head, this mount is not the right fit.

What hardware is included, and what tools do I need?

The Road Suppressor ships with 8× 5/8" 11×5 bolts, 8× 5/8" lock nuts, and 16× washers, everything needed to bolt the mount between a flat plate hitch and a flat plate trailer coupler. Installation takes under 60 seconds.

Does the Road Suppressor require any maintenance?

The Road Suppressor is maintenance-free. The polyurethane bushing system requires no lubrication or periodic service after installation.
