Skyjacker Suspension F17802KS-B Lift Kit with Conversion Black MAX Shocks - 8.5-Inch 4-Link and 8500

The Skyjacker F17802KS-B is a comprehensive 8.5-inch suspension lift system engineered specifically for 2017–2019 Ford F-250 and F-350 Super Duty 4WD gas-powered trucks. This kit features a full 4-Link conversion that replaces the factory radius arm suspension with upper and lower adjustable control arms, delivering significantly improved caster geometry, wheel articulation, and overall handling.

At the core of the front suspension upgrade are Skyjacker's Softride® variable-rate coil springs, engineered using proprietary processes to maximize wheel travel and ride quality while extending spring life. The adjustable Flex Link control arms are formed from 2-inch OD x 0.250-inch wall DOM tubing and feature a forked clevis end at the lower axle mount, allowing precise alignment tuning. A heavy-duty track bar relocation bracket captures the front crossmember on both sides to keep the axle properly centered under load.

Rear lift is achieved via Skyjacker Softride® leaf springs, with the system also including e-brake relocation brackets, bump stop spacers, rear braided stainless steel brake line extensions, and rear exhaust hanger brackets. All necessary mounting hardware and detailed installation instructions are included.

Shock absorption is handled by Skyjacker's Black MAX 8500 shocks, providing enhanced damping performance for both on-road comfort and off-road capability.
