Description
This new Lippert Rota-Flex fifth wheel pin box (176440) is a rubberized king pin coupler system engineered to improve towing comfort and reduce stress on your RV and tow vehicle. Designed specifically to fit Lippert 1116 frames, this pin box delivers up to 19,000 pounds gross weight capacity, making it ideal for mid-to-large fifth wheel trailers.
The Rota-Flex™ pivoting head design incorporates a proprietary rubber torsion compound that absorbs fore-to-aft movement (commonly known as chucking) and road shock. This allows the trailer and tow vehicle to move independently, maintaining a more stable and controlled towing experience.
By reducing vibration and impact forces, the Rota-Flex system helps protect your trailer frame and improve overall ride quality, especially during acceleration, braking, and uneven road conditions.
