Schuck Cushion Hitch Drawbars are high-capacity, shock-absorbing towing assemblies engineered to eliminate the harsh jerking and slamming ("chucking") typical of heavy-duty towing. Featuring internal polyurethane cushions, they absorb kinetic energy during acceleration and braking to protect your vehicle's drivetrain and improve ride comfort. Most models include a telescoping, swiveling drawbar that extends and swings side-to-side, allowing for quick, effortless hookups on uneven ground before automatically locking into the secure towing position as you drive forward.
