Fabtech 17 Ford F450/F550 4WD Diesel 6in 4Link Sys w/Coils & Perf Shks

Fabtech is known for building robust suspension systems that can handle tough conditions, and this 6-inch 4-Link Conversion system for your 2017 Ford F450 or F550 4WD Diesel is a prime example. If you're looking to significantly upgrade your truck's stance and capability for both on-road driving and off-road adventures, this kit is designed to meet those demands.

This system features heavy-wall, 2-inch diameter link arms built with 1/4-inch thick steel brackets. At the axle, these brackets include adjustable alignment cams, while at the frame, they utilize Fabtech's durable 5-Ton joints for smooth pivoting and a long service life. The kit also includes stout 1/4-inch thick steel frame brackets that securely mount the new suspension components without requiring cutting or welding. American-made coil springs are included, tuned to offer a compliant ride quality that balances highway comfort with off-road performance. To keep your axle centered with the added lift, a 1/4-inch thick steel bracket repositions the factory track bar, and a dropped Pitman arm, forged from high-strength steel, ensures proper steering geometry. Heavy-duty 1/4-inch steel brackets are also used to control suspension travel and prevent over-cycling, even under full compression impacts. The kit includes drop brackets to relocate the front sway bar, allowing full cycling of the link ends without binding. Brake line brackets reposition your factory lines to accommodate the new travel range, and a 1/4-inch thick steel bracket and support brace retain the factory steering stabilizer to help reduce tire shimmy. For the rear, steel lift blocks replace the factory ones for additional height, and American-made U-bolts secure the differential. Completing the package are extended-length, performance twin-tube shocks designed to provide a comfortable highway ride and capable off-road performance.

This comprehensive kit includes everything needed for the conversion: the 4-link arms, frame and axle brackets, American-made coil springs, performance shocks, a dropped Pitman arm, sway bar drops, track bar relocation bracket, and a U-bolt kit. It's designed to give your Super Duty superior articulation and wheel travel.
