The concept here is that two leaf springs are attached at both ends on the body while the center of the leaf springs are attached to the solid front axle. Sterring is achieved through steering knuckles on the end of the axle and on 4x4 vehicles power is transmitted through the steering axles to the wheels via universal joints and stub axles which engages the wheel hubs. |

This arrangement is over constrained and relies on deflection of the links and bushings in order for the body to roll. Because of this it acts like a built-in anti-roll bar, however the rate can not be adjusted without replacing the arms. This is something to be aware of when upgrading from factory to heavy duty aftermarket arms. A Panhard bar is traditionally used for lateral restraint. |
