Trailair was first to the market with air ride technology for fifth-wheel RVs and still leads the way with innovative fifth-wheel pin box technology. Our new Flex Air Pin Box combines our time-tested Trailair air ride technology with our Rota-Flex pivoting head to significantly reduce fore to aft movement and vertical tug-of-war between a fifth-wheel RV and tow vehicle.
- Oil Shock - As the air bag absorbs road shock and vibration, the oil shock absorber handles rebound action dampening kickback and controlling chucking.
- Air Ride Technology - Our integrated air bag acts as a buffer between the tow vehicle and coach to absorb road shock and vibrations that can damage an RV.
- Rubberized Compound - The durable rubberized compound provides an additional buffer to help protect the fifth-wheel RV from jarring motion.
- Pivoting Head - The heavy-duty pivoting head in its lower jaw controls the fore to aft movement known as chucking.
