The suspension system is a cartridge-type having an axle tube, a central tube and an anti-sway bar disposed in the central tube. Each cartridge has a torque absorption hub with a substantially cylindrical outer surface to match the inner surface of the axle tube. A plurality of square torsion bars are disposed between each torque absorption hub and the rotating arm. The arm is connected to the wheel. The torsion bars are disposed in a circular pattern about the central tube. The torsion bars pass through a bearing assembly connected with each rotating arm. The bearing assembly includes self-lubricating needle bearings. The relative position of the torque absorption hub with respect to the axle tube may be changed to change the road height of the vehicle. Torsion bars may be added or removed to change load characteristics. The unique shock absorber system uses a primary shock absorber to absorb relatively small shock forces, and a secondary shock absorber that is mechanically linked to the rotating arm to operate in a progressive fashion. This mechani- cal linkage includes a secondary arm and two lever arms. The secondary arm may be repositioned by a unique locking mechanism whenever the road height of the vehicle is changed. The entire suspension and shock absorber system is mechanically isolated from the vehicular frame and body by resilient rubber blocks to minimize the transmission of shock forces and road noise to the frame and body.
