Roadmaster Active Suspension is the only rear leaf spring suspension upgrade that converts basic “passive” leaf spring suspension to mechanical “active” suspension. Our system absorbs and dissipates load force energy, resulting in significantly reduced or eliminated rear squat caused by heavy loads. It improves vehicle stability, balance, traction and control, all with (or without) a load. Roadmaster Active Suspension adds critical strength to leaf springs, but will not compromise ride quality.
Roadmaster Active Suspension effectively eliminates Axle Wrap and Wheel Hop, by preventing the additional force of the increased torque, twisting the axle housing and by so doing, will now not allow the leaf springs to distort. RAS with the two powerful variable-rated coil springs will now hold the leaf springs in the original bowed shape. The distorted S-shape twist and subsequent hop, is thereby eliminated. Traction to the tires are now increased and torque is transferred to the ground efficiently.
When a vehicle is overloaded, the weight distribution shifts rearward, causing the rear to sag. The bulk of the load weight will now be transferred to the rear axle. This affects the steering, making it more floaty and less responsive. Roadmaster Active Suspension engages progressively to maintain the leaf spring arch, and applies proportionately to weight that is added to the bed or hitch of the truck. This unique design significantly strengthens and improves the ability of the rear suspension to handle heavy loads, resulting in reduction of rear squat by up to 3-4 inches.
