8.5" 2017-2022 Ford F250/F350 (w/Diesel Engine) 4-Link Lift Kit by Skyjacker

Skyjacker’s F17852K 8.5" 4-Link Conversion System for the Ford F250 and F350 Super Duty delivers an exceptional suspension upgrade that replaces the factory radius arm setup with fully adjustable upper and lower Flex Links. Built from 2” OD x .250 wall DOM tubing, these heavy-duty control arms allow precision caster tuning for improved handling and alignment on lifted setups.

This complete system re-engineers the suspension geometry for increased articulation, control, and ride quality. Skyjacker’s variable-rate Softride® coil springs are custom-tuned for Super Duty 4WD diesel applications, maximizing wheel travel and smoothing out on- and off-road driving conditions. A high-strength track bar relocation bracket secures the front crossmember to keep the axle centered, while a drop pitman arm corrects the steering angle. Additional components include sway bar lowering brackets, front bump stop spacers, front brake line extensions, and a steering stabilizer relocation bracket, all designed to provide precise handling and improved stability. The rear lift is achieved using a 5.5" block and U-bolt kit combined with Softride® Add-A-Leafs, ensuring a more level stance and enhanced load support. The system also includes E-brake relocation brackets, rear bump stop spacers, braided stainless rear brake line extensions, and rear exhaust hanger brackets.
