The premium pin box coupler:
Sidewinder's king pin locking mechanism moves the pivot position 22" rear of the pin box's attachment point. This enables Sidewinder to handle up to a 90-degree plus turn effortlessly. By moving the pivot rearward while keeping the load centered over the axles, the trailer tracks more closely to the truck. This reduces the need for extra-wide turns and allows short bed pickups to jackknife with no fear of contact. And it's all done automatically. Sidewinder also offers faster steering wheel response, making backing up easier than ever before. The pivoting pin box makes hook up possible at any angle. And since the towing position of the pin box arm is locked in line with the truck, you can make full use of the truck bed space, giving you extra storage space for fuel tanks, toolboxes and cargo.
Strength by design:
Don't let the slim looks fool you. Sidewinder has been built for strength. The C-channel design gives it more stability and strength than the standard pin box design. It also allows better load capacity and the ability to support heavier loads. Tested for real world conditions, Sidewinder has cleared rigorous testing by BOSCH automotive proving grounds and exceeds all SAE/CSA Standard 19K ratings requirements for RVs.
