The Reyco Granning model 102CC steel spring drive axle suspension has a proven track record as a rugged, reliable truck suspension. Rugged enough, in fact, to see duty on combat military vehicles as well. This single axle model is designed for severe-duty start-and-stop applications such as refuse trucks and snow plows. The leaf spring is shorter for minimal deflection and there is also an upper control arm to resist axle wind-up and pinion angle change due to acceleration and braking.
