The BOSS Torsion-Flex is the innovative fusion of the MEGA-DUTY drop hitch and TORSION-FLEX technology. 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 allows you to 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. Customers also greatly increased braking control because all of the weight on the tow vehicle and trailer is distributed evenly. Bumps, potholes, curves, hills, and even other drivers can be a hazard, and the BOSS keeps you under control when confronted with these conditions. Additionally, this product reduces metal fatigue caused by traditional towing that takes a toll on the trailer and its contents.
