The Ultra-Fab 35-946203 Trailair Air-Ride Pin Box (Model L05) transforms your fifth wheel towing experience by eliminating the harsh ride quality associated with rigid hitch connections.

Standard rigid hitch systems cause trucks and trailers to fight each other at highway speeds, with ride quality suffering as speeds increase and road conditions worsen. The Trailair system's simple yet effective design improves the overall ride for both the truck occupants and coach contents while protecting your fifth wheel trailer from damaging road shock. The result is improved handling, enhanced towing performance, and a significantly more comfortable travel experience.
