Fabtech 17-21 Ford F250/F350 4WD Diesel 4in 4Link Sys w/Coils & Perf Shks

If you're looking to give your 2017-2020 Ford F-250 or F-350 Super Duty (4WD Diesel) a significant suspension upgrade, this 4-Link System from Fabtech is a solid option. It's designed to lift your truck 4 inches while greatly improving its articulation and wheel travel, making it more capable off-road and on rough terrain. This system bolts directly onto the frame without requiring any cutting or welding, simplifying the installation process.

The heart of this kit is the heavy-wall, 2-inch diameter 4-Link arms, built with robust 1/4-inch steel brackets that securely attach to the frame. These links are paired with 1-inch Uniballs, a feature often found in race applications, which contributes to superior strength and allows for more suspension movement. Fabtech includes their replacement Coil Springs designed to work with this system, ensuring a balanced lift and ride. To round out the front suspension, you'll find a Trac Bar relocation bracket and Sway Bar drops. The rear gets a block and U-bolt kit to achieve the desired lift height.

This comprehensive kit also comes with front and rear Performance Shocks, tuned to complement the new suspension geometry and provide a more controlled ride. You'll also receive a new Pitman Arm. While this kit is designed for a direct bolt-on installation, it's a complex system, so referring to the manufacturer's instructions for specific details is always recommended.
