"The GEN-Y HITCH The BOSS TORSION-FLEX 3"" Shank 21K Hitch with Dual-Ball and Pintle Lock gives you the innovative fusion of the MEGA-DUTY drop hitch and TORSION-FLEX technology. The BOSS can apply to many types of customers, including oilfield fleets, heavy-duty construction contractors, and government vehicles. 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. The 90% smoother ride lets you glide instead of bounce, therefore increasing gas mileage. Since the tow vehicle and trailer track independently, customers gain greater control and safety through the reduction in sway and trailer bounce. Even weight distribution increases braking control. Bumps, potholes, curves, hills, and even other drivers can be a hazard, and The BOSS keeps you under control in these conditions. Additionally, this product reduces metal fatigue caused by traditional towing that takes a toll on the trailer and its contents. Consequently, The BOSS increases quality of life and holds outstanding value. 21,000-lb. towing capacity 2,400-lb. tongue weight Dual Ball: 2"" and 2-5/16"" Designed for 1.5"" or smaller lunette rings Fabricated with heavy-duty steel Coated with durable silver-vein powder coat Heavy-duty rubber TORSION-FLEX cords"
