Lippert 369535 Flex Air 21K Pin Box – Long Jaw Air Ride 5th Wheel Coupler with Rota-Flex Head and Shock Absorption

Description

The Lippert 369535 Flex Air pin box combines Trailair Air Ride technology with a Rota-Flex pivoting head to improve towing comfort for 5th wheel RV owners. Rated for 21,000 lb gross weight capacity, this long jaw pin box helps reduce fore-to-aft movement, vertical tugging, and road shock transferred between the tow vehicle and trailer. || An integrated air bag absorbs road vibration while the internal oil shock absorber manages rebound action and dampens kickback. The heavy-duty pivoting head helps control chucking forces that commonly occur during acceleration, braking, and uneven road conditions. A rubberized compound further softens jarring movement for smoother towing performance. || Designed for heavy-duty 5th wheel towing applications, the Flex Air system improves ride quality while helping protect trailer components from repetitive road impact. The long jaw configuration provides compatibility with designated mounting applications and delivers enhanced towing stability over long travel distances.
