Description
This new Lippert Rota-Flex™ fifth wheel pin box (328329) is a rubberized king pin coupler system designed to improve towing comfort and reduce stress on your RV and tow vehicle. Built specifically to fit Lippert 1621 frames, this heavy-duty pin box delivers a 21,000 pound gross weight capacity, making it ideal for larger fifth wheel trailers.
Product Details
- The Rota-Flex™ pivoting head design uses a proprietary rubber torsion compound to absorb fore-to-aft movement, commonly referred to as chucking, as well as road shock and vibration. This allows the trailer and tow vehicle to pivot independently, while maintaining a stable and level connection at the king pin.
- By minimizing vibration and impact forces, this system helps improve ride quality, reduce driver fatigue, and protect the trailer structure during towing.
