Very low frequency (1.25 Hz) operation protects load, vehicle, and driver from road shocks.

|
Suspension is completely non-reactive: wheel hop is eliminated, braking performance is improved, tyre life is increased; suspension is ideal for high-torque engines.
|
|
|
Axle is secured by an "A" frame that controls fore, aft, and sideways movement, while permitting full vertical and roll axle travel.
|
|
|
Lightweight, high-strength tubular anti-roll bar is mounted in rubber bushings.
