Improved Trailer Ride Improves Truck Ride - A Great Truck Accessory

Your RV trailer is designed with great attention to comfort, looks, and numerous amenities. But, most manufacturers overlook ride quality. Improving ride quality in the trailer reduces wheel bounce and shock transmission to the trailer. Reducing structural fatigue can reduce your maintenance cost and damage to sensitive equipment. Items in the trailer are less likely to move around.

Reducing shock transmitted to the trailer reduces shock transmitted to your cab.

Trailair Center Point air bag dampens two axles and dissipates shock without transmitting it to the trailer frame.

Trailair's Center Point system avoids air leak problems with a safety system design. The air spring cannot collapse on itself even in the event of air loss and the shape allows for oscillation in travel. The design allows for airless operation without damage. Air leaks will cause the ride will suffer, so the sooner leaks are fixed the better. Also, all the pneumatics on these systems are D.O.T. approved. The components used in Trailair's Center Point system are industry standard equipment and easily obtained for quick repairs.

The air spring is made by Firestone and is the same tuff quality as air springs on the big over the road rigs, just smaller. The air springs are extremely durable. We use a 25C air spring that can be found in Firestone's Ride Rite Catalog.

Trailair's Center Point System is low maintenance. The system itself is a dry system requiring no lubrication. The standard parts of the trailer's factory suspension will still need to be lubricated. The pneumatics are thought to have a life of 200,000 miles.

Roush Anatrol, a division of Roush Industries, Inc., tested the Trailair Center Pont system and states, in a 2003 report for Trailair, the stability and handling of the tow vehicle are much improved.

Additional Trailer to Truck Dampening

Trailair provides additional comfort with the Air Ride Pin Box. (See G13-4) Air Ride Pin Box
