If you work hard and play harder outdoors, you need taller tires for ground clearance. Gain ride height and improved ride quality with this 4-inch lift. Add more aggressive 35s off-road tires for more ground clearance then go get down and dirty. Skyjacker's legendary Softride(R) technology engineered processes achieve maximum wheel travel, ride quality and extends the long-lasting life of the coil spring. The process starts with 5160H chromium alloy material, an advanced method of shot pining and a presetting process. This takes any fatigue or stress off the spring and eliminates sagging. Radius arm drop brackets lower the OEM radius arms mounts at the frame to maintain the correct caster specifications for proper alignment. An ultra heavy-duty track bar relocation bracket captures the front crossmember on both sides to prevent movement in this critical high-stress area and to keep the axle centered. The sway bar links realign the front sway bar working angle to achieve maximum sway control. Drop spacers reposition the front bump stops. Front brake line brackets and braided stainless steel brake lines correct and reposition the brake lines. A heavy-duty steering stabilizer relocation bracket corrects and enforces the stabilizer connection. Hydro steering stabilizer included. Softride(R) Technology leaf springs have tapered leafs to distribute loads more evenly and to create more flex at the leaf ends. Teflon(R) wear pads between leafs and bolt style spring clips prevent binding and eliminate friction. Shocks are a key link in-between the chassis and your suspension. Front and rear damper capacity enhanced with ADX 2.0 Adventure Series Remote Reservoir Aluminum Monotube Shocks. ADX 2.0 has a race-inspired full-displaced valving system. Nitrogen charged with Internal Floating Piston Technology = Quickest Shock Reaction Time Ever. Together this complete kit maintains the factory geometry angles, alignment specifications and structural strength.

4 in. Suspension Lift System With ADX 2.0 Remote Reservoir Monotube Shocks.

Skyjacker 4In SYSTEM 08 F250 4WD GAS - F8401KS-X FAQ

Install and care: lift kits

Before you start

  • Read the maker's guide for the tire size it clears and whether longer shocks or driveline parts are called for.
  • Book an alignment and, on trucks with cameras or adaptive cruise, a re-aim of those systems.

Do

  • Torque every bolt to the maker's figure and re-check after the first drive.
  • Align the truck once the height has settled.

Don't

  • Don't run a larger tire than the kit is made for without checking the clearance.
  • Don't skip the driveline parts the maker says a taller lift needs.
