- Cross-reference Part #: 90603290-II
The Trailair® Air Ride™ Pin Box acts as a buffer between the tow vehicle and RV, arresting the impact of road shock and stabilizing the towing performance. How? Simple — the unique scissor action allows the air bag to absorb road shock and vibration while the gas shock handles the rebound or bounce effect, giving RVers a better, smoother ride.
