Abstract
A truck cab suspension system provides improved durability of the truck cab structure by reducing twisting forces applied to the cab frame from the suspension system. The suspension system provides support to the rear sill of the truck by positioning two air springs on either side of the vehicle center line under the sill and two shock absorbers aligned along the vehicle center line between the air springs. The forces applied to the cab frame rear sill balance one another avoiding twisting.
