The Flex Air® Pin Box unifies time-tested Trailair® Air Ride technology with the Rota-Flex™ pivoting head to reduce chucking and vertical tug-of-war between a fifth-wheel RV and tow vehicle, providing a more comfortable ride. Flex Air utilizes an air bag and rubberized compound to absorb road shock and vibrations, an integrated oil shock absorber to dampen kickback, and a pivoting head to control chucking.

The Air Ride® Pin Box acts as a buffer between the tow vehicle and RV, arresting the impact of road shock and stabilizing the towing performance. How? Simple -- the unique scissor action allows the air bag to absorb road shock and vibration while the gas shock handles the rebound or bounce effect, giving RVers a better, smoother ride.

From the same minds at Trailair that brought you the Air Ride Pin Box and the Equa-flex® rubberized equalizer comes Rota-Flex®, a rubberized and pivoting pin box designed to enhance and smooth your ride. Pivoting head significantly reduces fore to aft coach movement. A rubberized torsion compound in the pin box head absorbs motion and vibration caused by road shock, that would otherwise be absorbed by your RV. This saves you $$$ in the long run! Now with powder-coated lower jaw!

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.

A Capture Plate is a required component of the SuperGlide fifth wheel towing system. This plate is attached to your trailer's skid plate. When you're hooked up into your SuperGlide hitch and ready to tow, it isolates the rotation of your trailer's king pin in the hitch. Movement and rotation is then transferred to the automatic cam action of your SuperGlide hitch, moving it away from the cab along its rails to prevent the trailer from contacting the cab of your truck! The #331725 is used with Lippert's Helux pin boxes that are 13-3/16" wide.
