Medium Duty Weight Distribution System by BulletProof

Take control of your towing setup with the BulletProof MDWD Medium Duty Weight Distribution System — a complete solution designed to improve trailer handling, reduce sway, and enhance overall safety. Built for serious towing applications, this system is engineered to distribute trailer tongue weight more evenly across the tow vehicle’s axles, minimizing sag and improving braking and steering response. Whether you're hauling a large camper or heavy equipment trailer, this system ensures a more stable and confident towing experience.

With sway control integrated directly into the design, side-to-side trailer movement is greatly reduced, increasing safety at highway speeds and on rough roads. Unlike many systems, ours allows for full maneuverability with no turning restrictions and backing up is permitted while the system is in place. It’s also compatible with electric and surge brakes for maximum versatility and convenience.

Installation is fast and simple — no drilling required. The adjustable spring bar brackets fit trailer frames from 3" to 6", while the included 2-5/16" ball is pre-installed, saving you time and hassle. Whether you're using a BulletProof Medium, Heavy, or Extreme Duty hitch, this system is the perfect addition to your towing setup. (Note: Not compatible with aluminum or light-duty hitches.)
