Product Details

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. This innovative air-ride system acts as a buffer between your tow vehicle and trailer, arresting the transfer of road impact to produce smooth, stabilized towing performance.

Key Features:

  • 21,000 lb gross vehicle weight capacity for heavy-duty fifth wheel trailers
  • Air-ride suspension system absorbs road forces and eliminates "diving board" effect
  • Unique scissor action design allows air spring to dissipate impact forces
  • Integrated shock absorber handles rebound effect for controlled movement
  • King pin coupler type with included king pin
  • Dimensions: 41.763 inches length x 11-7/8 inches width
  • 2-row bolt pattern with 7-7/8 inch horizontal mounting bolt spacing and 2 inch vertical spacing
  • Black powder-coated finish for durability and corrosion resistance
  • Replaces Fabex 765 and RBW 7028 pin boxes

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.

I ordered Thule Aero Blade Load Bars as part of a bike rack for my Infiniti EX35. The part was order on Saturday, 04/14, and arrived at my doorstep on Tuesday, 04/17. And that was by FEDEX Ground shipping. Very very quick, and the right part to boot. Excellent service.
