With the Flex Air Pin Box by CURT, you can stabilize your 5th wheel trailer or RV with ease. The Flex Air features an internal air bag and built-in strut that team up with a rubberized pivoting head to reduce chucking and virtually eliminate bounce and jarring. The pivoting head regulates movement of the king pin within the hitch while the rubber compound absorbs road shock, giving you a smooth ride that keeps things in control through harsh roads. Leave unwanted movement right at home!
