Skyjacker lift kits use Softride technology leaf springs manufactured using tapered leaves to yield a lower spring rate and better travel, Teflon wear pads to help reduce interleaf friction, a "bolt" style clip to reduce leaf friction and shotpeening to compress the steel and increase its tensile strength. The 6" lift kit includes front leaf springs, brake relocating bracket, all hardware and a rear block and/or add-a-leaf. Transfer case lowering kit may be needed for 6" lifts. Shocks, steering correction and sway bar drop sold separately. A pitman arm is recommended over a steering arm for the 1 Ton vehicles to eliminate bump steer.
