      Aggressive Looks and Performance. Give your Super Duty aggressive off-road looks and performance to match with the Fabtech 4-Inch Radius Arm Lift System with Dirt Logic Shocks. This suspension lift kit is designed to add 4 inches of lift to your truck, while maintaining correct suspension geometry and a comfortable ride. This allows you to negotiate more challenging off-road trails without compromising ride quality when on the highway. Additionally, this lift kit enables you to use larger 35-inch tires for that aggressive off-road look.

      Front and Rear Dirt Logic Shocks. The Fabtech 4-Inch Radius Arm Lift System includes front and rear Dirt Logic shock absorbers. These shocks are designed to work your truck, providing the right amount of dampening for a more comfortable ride both on and off-road. These shock absorbers are built to take a lot of punishment thanks to a 2.25-inch OD stainless steel body, 2.0-inch OD billet aluminum piston, and a 0.87-inch thick NitroSteel piston rod.

      Brawny Coil Springs With 4 Inches of Lift. The 4 inches of lift provided by the Fabtech Radius Arm Lift System is courtesy of a pair of brawny coil springs. These coil springs are constructed from high-grade carbon-steel for superior durability. Also, these coil springs are finished in a tough, black powder coating for excellent rust protection.

      Proprietary Radius Arms. The Fabtech Radius Arm Lift System uses proprietary radius arms. These twin radius arms offer ideal positioning of the coil springs with the axle. The result is ideal suspension geometry and better steering feel. These radius arms are built from superior-grade steel, and come with machine-formed dimpled side plates for increased stiffness.

      Strong Rear Lift Blocks. Rear lift is provided by Fabtech 4-Inch Radius Arm Lift System’s included rear lift blocks. These sturdy blocks are made from a specialized alloy that’s extremely resistant to compression, as well as cracking. These lift blocks also receive a black powder-coat finish for corrosion prevention.

      No-Frills Installation With Cutting and Trimming. Installing the Fabtech 4-Inch Radius Arm Lift System With Dirt Logic Shocks is a relatively no-frills process that uses the included installation hardware. That being said, you will need to perform some cutting and drilling for proper fitment. Additionally, installation can take several hours or the better part of a day depending on your mechanical abilities. Consequently, professional installation is recommended.

      Includes a Limited Lifetime and 1-Year Warranty. The Fabtech 4-Inch Radius Arm Lift System With Dirt Logic Shocks’ hard components include a limited lifetime warranty, while the shocks absorbers are covered by a 1-year limited warranty. Please visit the manufacturer’s website for more details.

      Application. The Fabtech 4-Inch Radius Arm Lift System With Dirt Logic Shocks fit all 2017-2022 Ford F-350 6.7L Super Duty 4WD models.
