Skyjacker makes this Leaf Spring 4in Lift for the 1999-2004 Ford F-250 Super Duty 4WD. It sets ride height and carries the load at the axle.

Key Features

  • Softride 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 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.
