Lippert M19 Air Ride Pin Box, 21K • 155943

Product Details

Trailair® introduced air ride technology that would revolutionize the RV industry. Since then, many pin boxes have come and gone, but the Air Ride still stands tall as the leader in air ride technology. 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, more smooth ride.
