Lippert Components L05 Flex Air® 18K Trailair Pin Box
Looking for a more comfortable and smooth towing experience? The Flex Air® Pin Box by CURT® is the perfect solution. Designed to stabilize your 5th wheel trailer or RV, this innovative product features an internal air bag, built-in strut, and rubberized pivoting head to reduce chucking and eliminate bounce and jarring during towing.
The Flex Air® Pin Box is engineered with advanced Air Ride™ technology and Rota-Flex™ pivoting head, which significantly reduces fore to aft movement and vertical tug-of-war between your 5th wheel RV and tow vehicle. The internal air bag moves in a scissor-like motion to absorb vibrations, while the rubber compound softens jarring movement. An oil shock absorber handles rebound action, dampens kickback, and controls chucking. The result is a smooth and comfortable towing experience even on rugged roads.
The Flex Air® Pin Box has a gross trailer weight of 18,000 lbs. and is designed to replace Lippert 1621 pin boxes. It uses the same bolts as the original pin box, making installation a breeze. Constructed with high-strength steel and a black powder coat finish, the Flex Air® Pin Box is durable and rust-resistant, ready for any adventure you have in store.
