Description

The Lippert 328484 Flex Air M15 pin box is designed to improve fifth wheel towing performance through a combination of air ride suspension and integrated shock dampening technology. With an 18,000 lb weight rating, it helps reduce the transfer of road shock, vibration, and trailer movement to the tow vehicle. || An adjustable air bag cushions impacts from uneven pavement while the internal shock absorber manages rebound forces and trailer bounce. Together, these components help reduce driver fatigue and improve towing comfort during extended travel. || Manufactured from heavy-duty steel and designed for M15 mounting applications, the Flex Air system serves as a direct replacement for compatible fifth wheel pin boxes. Its proven air ride design helps protect trailer contents while improving overall towing stability.
