About this product
Improve the quality of your ride with the CURT® Rota-Flex™ 5th wheel pin box. While chucking often occurs as a result of the king pin jerking inside the hitch, the Rota-Flex features a pivoting head that controls back and forth movement of the king pin within the hitch which reduces chucking and leads to a smoother ride. What makes this CURT pin box particularly unique is that chucking is significantly reduced as a result of the pin box head moving instead of the king pin itself. The Rota-Flex also contains a robust rubber compound in its head that absorbs road shock and vibrations, resulting in less strain and reduced wear and tear on your trailer as you travel.
