Eliminate Axle Wrap
Axle Wrap, Bad. Roadmaster, Good!
Axle wrap occurs when the rotational force of the tires causes the axlehousing to twist or rotate. This rotation forces the springs to bend into an S-shape. When the axlehousing rotates far enough, forces cause the tires to loose traction, and jump, or “hop”. Once traction is lost, the springs snap back into their original positions.
This happens over and over until the truck gains better traction or the driver reduces torque input by letting off the throttle.
Roadmaster Active Suspension effectively reduces axle wrap and wheel hop by “absorbing” the added force of increased torque while holding the leaf springs in their original bowed shape. The S-shape twisting, and subsequent hop, is thereby greatly reduced. Traction is increased because tires transfer torque to the ground efficiently.
The improvement to driving performance will be most noticeable when accelerating on hill climbs or at times of rapid deceleration, such as hard braking.
By reducing axle wrap, RAS also minimizes wear and tear on several truck components including internal axle assemblies, tires, shocks, shackles, U-joints and leaf springs… ultimately saving $$$s.
