Get the best of both worlds with this authentic RAS® Heavy Duty RoadActive Suspension kit -- the only solution that strengthens leaf springs by up to 50% while providing a more smooth, controlled ride at all times. Unlike other suspension upgrades that need constant adjustments & maintenance or negatively impact unloaded ride, RAS® eliminates squat, excessive bounce and body roll-- without hassle or sacrificing comfort .

This 3-in-1 system offers the benefits of a helper spring, sway bar, and traction bar at the fraction of the cost of other upgrades. With a quick 1-hour installation and zero maintenance, it's the simplest most effective way to reduce squat and improve your truck's towing/hauling performance. 

 

RoadActive Suspension provides a 30 day money back guarantee, from date of purchase. However should the kit be returned, it must be re packed in the original packaging with all components included. On orders with free shipping (where shipping was paid for by RoadActive Suspension), refunds will reflect the invoiced amount, minus that shipping cost billed to us by our shipping provider. In addition, the customer will be responsible for the return freight charges.

It works with your suspension — not against it.

We already know what you're going to ask.

RAS uses a variable-rate tension coil spring that attaches directly to your rear leaf springs. It works like a muscle, progressively engaging as load or force is applied. This keeps the leaf springs in an upright bowed position to prevent sag, improve stability, and enhance bounce isolation.

Most applications see a 2–3" reduction in rear squat. The exact amount will depend on multiple factors such as vehicle size, load size, load placement, leaf spring condition, and the tension setting of the RAS.

Expect same-as or better-than-stock unloaded ride with less bounce and more control.

Yes — in as little as 45–60 minutes with jack stands and hand tools. No drilling, no air lines, no maintenance.

Airbags add complexity, cost, and ongoing maintenance. Other helper springs only address sag and can compromise ride comfort.RAS is 3-in-1:it controls squat, reduces sway, and improves traction — all with zero maintenance.
