The beauty and reliability of the Trailair® air ride systems is their simplicity. The air ride pin box acts as a buffer, arresting the transfer of road impact between the tow vehicle and the coach to produce smooth, stabilized towing performance.

Generally, a truck and a trailer connected by a ridged hitch system (basically any standard fifth wheel or ball connection) will tend to fight each other as you travel at highway speeds. The faster you go and the worse the road conditions, the more the ride quality suffers. Not only are you dealing with road forces from traveling down the road, but also additional forces are created as the two vehicles fight each other causing a "diving board" effect. The Trailair® coupler's unique scissor action allows the air spring to absorb these forces and dissipate them and for the shock absorber to handle the rebound effect. The result is an improved ride for the truck and it's occupants, the coach and its contents.

The Trailair® Pin Box comes in three (3) styles and 21 variations. To determine which pin box you need click the link below:
