Cush Suspensions offers a variety of full truck and trailer lift axle suspensions, as well as add-on lift kits for most suspensions in the market. Even if we do not have a lift kit already design, we'll engineer one just for you!

We offer steerable and non-steerable lift axle suspension systems. Lift-able auxiliary axle suspensions help add payload capacity on trucks and trailers, but because of the wide variety of state and local regulations applicable to axle weights and spreads, you need a company that knows what they're doing.

An enormous amount of engineering is required to ensure you receive the right solution for your particular application. Cush Suspensions will design the right lift axle suspension for your specific needs!

Benefits of Auxiliary Lift Axle Suspensions

• Improved Fuel Economy: Eliminate resistance of one axle's tires when empty or lightly loaded.
• Increased Payload Support: When you are hauling more weight, the lift axle helps better disperse the increased payload.
• Improved Brake & Tire Wear: When the lift axle is in-use, it helps reduce wear and tear on the other axles.
• Load Transfer Adjustments: Lifting and lowering the axle height allows you to change the center of mass for more efficiency.
• Reduced Toll Costs: Certain states allow for reduced toll rates when the lift axle is not in-use.

Utilizing lift axles allows you to increase the load capacity of your trailer, eliminating the need for multiple trips, and reducing operational costs.

According to SAE International, "The SAE Fuel Consumption Test Procedures Type II (J1321) was used for fuel consumption track test evaluations. The tests were conducted on unloaded two-axle van semi-trailers, four-axle van semitrailers, and B-trains, and resulted in fuel savings of 1.3% to 4.8%, depending on vehicle configuration and the number of axles lifted during the test."
