REESE Sidewinder Pin Box

The REESE Sidewinder Pin Box, a premium towing solution, is specifically designed for short bed truck owners. It eliminates turning and clearance issues, enabling up to 90-plus-degree turns without leaving the truck cab. The patented pivoting mechanism locks the trailer's king pin to the fifth-wheel hitch, shifting the pivot point 22 inches rearward for increased clearance. This innovative design allows for automatic tracking during forward or reverse towing, maintaining load stability and eliminating the need for a fifth-wheel slider system.
