Description
Ultra-Fab 35-946203 Trailair air-ride fifth wheel trailer hitch pin box (Model L05) is engineered to dramatically improve towing comfort and stability by reducing road shock and vibration between your truck and trailer. Designed with a proven air ride suspension system, this pin box acts as a buffer, minimizing the transfer of harsh road impacts for a smoother, more controlled towing experience.
Product Details
- Unlike rigid hitch systems that can create a “diving board” effect between the truck and trailer, the Trailair® system uses a scissor-action mechanism combined with an air spring and shock absorber to absorb and dissipate forces. This results in improved ride quality, enhanced handling, and reduced stress on both the tow vehicle and trailer structure.
- Ideal for heavy-duty fifth wheel applications, this model supports up to 21,000 lb gross vehicle weight capacity, making it a reliable upgrade for improved towing performance and long-term durability.
