All You Need to Know About Roadmaster Active Suspension
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.

Simplify Load Carrying
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.
We at Roadmaster Active Suspension (RAS) came up with a solution that works wonders, to improve not only vehicle load carrying and preventing bottoming out, but will also greatly improve stability, handling, eliminate axle wrap and wheel hop, all without stiffening the ride. Customers get all these advantages in just one product. Since it’s North American introduction in 1998, RAS has sold over half a million kits world wide ‘with rave reviews”.
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 will also affect the steering, making it more floaty and less responsive. The conventional approach to increasing the load carrying of a truck, van or SUV has been to increase the stiffness of the rear leaf springs or by resisting the weight at the frame. This does increase the carrying capacity, but at the expense of ride quality. 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.
The kit comes fully assembled out of the box, with easy to follow instructions. Installation is simple taking less than an hour, with no drilling, cutting or welding and once installed requires no maintenance. RAS also comes with a full 30 day money back guarantee.

How RAS Works
RAS converts basic “passive” leaf springs suspension to mechanical “active” suspension. Once installed, the powerful tension coil springs will hold the rear leaf springs in their original designed optimum bowed position. When strain from a load or vehicle weight shift is applied the powerful Coil spring stabilizers come into action immediately absorbing the force of the load. Being variable rated, the greater the strain on the leaf springs, the greater counter-assistance force from the RAS unit is applied.
RAS is the only system that instantly absorbs and dissipates load force energy, resulting in significantly improved vehicle load carrying, stability, balance, traction and control, with or without a load. RAS will add critical strength to the leaf springs without compromising ride quality. It will also eliminate bottoming out axle_wrap and wheel hop and greatly improve overall handling, by reducing sway and dangerous body roll when cornering and in cross wind conditions.
Tow vehicles that consistently operate under load, will also benefit from improved fuel efficiency and extended tire and suspension component life. The installation is a simple retrofit to most pickup and vans with rear leaf spring suspension, with up to 1.5 ton load carrying capacity. Once installed the RAS requires no adjustments or maintenance.
With a (RAS) system installed, your towing will become so much more enjoyable, safer and you will arrive at your destination with reduced driver fatigue.
