A simple add-on spring for rear leaf springs can boost fuel efficiency, extend tire life and reduce wear and tear on a vehicle's rear end, says Clive Schewitz, Roadmaster Active Suspension (RAS).
"Roadmaster Active Suspension can reduce fuel use by up to 20 percent while extending by actively helping carry the load," says Schewitz. "If you've ever had a broken axle or other problems with rear suspension, you'll really appreciate the Roadmaster."
He explains that when a vehicle is under load and the leaf springs flatten out, the tires flex and bulge. This increases the tire footprint and adds roll resistance similar to an under-inflated tire. The Roadmaster helps carry the load, turning the passive leaf spring suspension into an active one.
"The system increases load carrying ability by boosting the capacity of stock rear leaf springs without stiffening the ride," says Schewitz. "It eliminates bottoming out, just like an air system, but it never needs adjustment. With a load or without one, Roadmaster reduces sway and roll just like an anti-sway bar and eliminates axle wrap and wheel hop like traction bars. Customers get all of this in just one product."
The simple-to-install kit comes already assembled. Once the rear wheels are removed and the retainer plate and U-bolts on the leaf springs are removed, installation is simple. The coil spring assembly is installed over the rear leaf spring mount and secured in place with the re-installation of the retainer plate and U-bolts. Once installed, it's easily adjusted and set for maximum load.
Until a load is applied to the vehicle, the Roadmaster has no effect. When the arch in the leaf springs begins to flatten out under load, the variable rate coil spring goes to work.
It's available for all sizes of pickups and vans from 1/4 ton to 1 1/2 ton. The exception is cab and chassis box vans.
Prices range from $305 to $325. Retail locations can be found on the company website.
