Fabtech 19-20 Ford F450/550 4WD Diesel 6in 4Link Sys w/4.0 & 2.25 Dl

Fabtech's 6-inch 4 Link Conversion system for the Ford F450 and F550 Super Duty is designed for on and off-road demands. It converts the front suspension to a 4-Link system, improving on-road driving with less caster change and increased off-road articulation compared to a Radius Arm system. Features include 2-inch OD heavy-wall link arms, 1/4-inch thick steel axle brackets, adjustable alignment cams, and Fabtech's 5 Ton joints. The system incorporates Dirt Logic 4.0 coilovers with 4-inch diameter stainless steel bodies and 1.25 NitroSteel piston rods. American-made coil springs are included to handle the F450/F550 weight and provide a superior ride.
