Description
Skyjacker Rear 3in Leaf Spring 2017 Ford F-250/F-350 4 Wheel Drive
Softride(R) springs use only American steel and the individual leafs of each spring are shot-peened with hard steel pellets at very high velocities. This shot-peening compresses the surface of the steel thereby increasing the tensile strength of the spring. Without this shot-peening procedure, the maximum wheel travel and ride quality could not be achieved without sacrificing the life of the spring. Softride(R) springs use bolt style spring clips, eliminating friction. Other spring designs use the c in. style bend clips which bend tightly over the spring leafs causing binding and friction. Skyjacker(R) Softride(R) springs taper over the entire length of the leaf creating more flex at the leaf ends. This tapering distributes loads more evenly over a greater area and reduces the tendency for one leaf to dig into the leaf above it.
