This suspension has leaf springs at all four corners. The front leafs are mounted below the axle; the rear leafs are mounted on top of the axle. Due to the weight of these rigs, replacement heavy-duty front springs are used. Rear lift is via either lift blocks, an add-a-leaf / block combination, or Superide springs. Other components include Urethane front spring eye bushings, front brake hose relocating brackets, and shocks. The dropped pitman arm is optional.
