Sidewinder is the premium pin box coupler designed specifically for short bed pickups. The nimble and quick design automatically eliminates turning and clearance headaches. Now you can make up to 90 Degree turns without exiting the truck. Without throwing a switch. Without pushing a button. Sidewinder’s kingpin locking mechanism moves the pivot position 22 Inch rear of the coupler’s attachment point. This enables Sidewinder to handle up to a 90 Degree 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 arm of the pin box 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.
