GEN-Y’s Boss Adjustable Drop Hitches start at 4,000kg towing capacity and go up to 7,000 kg towing capacity. The Torsion-Flex Drop Hitch is the best hitch for ultimate control and safety while towing any bumper style trailer on the market including pintle style couplings. In addition to being heavy-duty, fully adjustable, and versatile, the BOSS also contains rubber torsion arms. Therefore, only 10% of the trailer inertia transfers compared to 100% when using a hard connection hitch.
