The Lippert Components M19 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. The unique scissor action of this pin box 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. With a 21,000 lb. tow capacity and a long jaw to protect your vehicle from damage, this Lippert pin box can potentially save you from having to pay for costly repairs.
