Lippert Components L05 Rota-Flex™ 18K Trailair Pin Box

Upgrade Your Towing Experience with the CURT® Rota-Flex™ 5th Wheel Pin Box

Take your towing game to the next level with the Rota-Flex™ 5th Wheel Pin Box from CURT®. This innovative product is designed to provide a smoother, more comfortable ride for your trailer, and make your journeys more enjoyable.

One of the most common issues that trailer owners face is chucking, which is caused by the jerking motion of the king pin inside the hitch. However, the Rota-Flex™ solves this problem with its unique pivoting head, which controls the back and forth movement of the king pin within the hitch, reducing chucking and leading to a smoother ride.

The Rota-Flex™ also features a robust rubber compound in its head that absorbs road shock and vibrations, reducing strain and wear and tear on your trailer as you travel. With a gross trailer weight of 18,000 lbs., this pin box is designed to replace Lippert 1621 or 1621HD pin boxes and is constructed with high-strength steel and a black powder coat finish that protects against rust, giving you the power to tow steadily through all the adventures that lie ahead.

One of the best things about the Rota-Flex™ is its simple installation process. It uses the same bolts as the original pin box, so there’s no need for additional hardware. The Rota-Flex™ comes completely assembled and ready for installation, making the process quick and easy.
