Center Point Suspension

Patent Applied For

The revolutionary new Trailair Center Point Suspension gives new meaning to comfort for standard leaf spring suspensions. The enhanced dampening and equalization permits the axles to work together, not oppose each other like standard spring suspensions.

Moving to an air ride for trailers with leaf springs has never been so easy or so reasonably priced.

• Greatly improved ride quality which relieves stress to the total trailer.
• Complete load equalization.
• Greatly reduced side to side swaying of trailer.
• Optimum braking efficiency.
• Longer tire and brake life.
• Minimal maintenance required.
• Dramatic improvement in tow vehicle ride and passenger comfort.
• Protection of RV structure and contents.
• System mounts completely under the trailer frame and skirting.

Center Point adapts to both tandem and tri-axle* double-eye leaf spring suspensions.

Tandem	Tri-Axle

Center Point installs into the existing center frame hanger, shown above, utilizing the pivot bolt hole of the standard toggle/equalizer combined with lateral stiffing plates that bolt in the perpendicular direction to increase stability. Refer to the application page for more details.

* Some additional mounting components are provided for the tri-axle version and specific hangers sizes as well as settings are required.

Once again, GREAT!! We know it... but let us explain it in more detail. As the trailer is pulled by the tow vehicle, the tires recieve all the input from the road and transfers this input into the leaf springs. This force and motion is transfered into each end of the leaf spring. The majority of this force and motion is working its way to the center because that is the path of least resistance through the spring to the center shackles. This in turn causes the shafts of Center Point to rotate, thus expanding and contracting the horizontally mounted air spring. It is at this moment that the force and motion is absorbed and dampened without being disapated into the frame of the trailer. In addition, a lot of movement by the tires and axles only minimally affects the frame of the trailer and everything above it. Result, a much better performing suspension system and a much smother ride.
