Fabtech 17 Ford F450/F550 4WD Diesel 6in Rad Arm Sys w/Coils & Dl Shks

When you're looking to give your 2017 Ford F450 or F550 4WD Diesel a significant lift and a more robust suspension, this 6-inch Radius Arm System from Fabtech is a complete package. It includes replacement front coil springs designed for a compliant ride, a dropped pitman arm, sway bar drop brackets, rear lift blocks, and U-bolts. You also get Fabtech's Dirt Logic 2.25 shocks, featuring stainless steel bodies and NitroSteel piston rods for excellent corrosion resistance and durability, aiming to improve your ride quality both on and off the pavement.

This system goes beyond just lifting your truck; it's engineered to handle the demands of larger tires and the unique suspension needs of the F450 and F550, which are built tougher than their F250/F350 counterparts. The radius arms themselves are constructed with tubular steel and feature dimple die side plates for added strength, plus an adjustable alignment cam for precise caster adjustment. Fabtech also includes a track bar relocation bracket to keep your front axle centered under the increased lift height, and drop brackets for the front sway bar to ensure proper cycling without binding. To keep your factory brake system intact, brake line brackets are included to reposition the lines without needing to bleed the system. Additionally, steering stabilizer brackets are provided to help reduce tire shimmy by retaining the factory F450 or F550 long travel steering stabilizer.

Completing the kit are rear lift blocks and American-made U-bolts to securely attach the rear differential. This comprehensive system aims to provide a strong, well-designed upgrade that balances on-road comfort with off-road capability, all while maintaining factory steering stabilizer and brake line functionality.
