2005-2007 Superduty 8" 4-Link Conversion Kit with NX2 Nitro Shocks (BDS531H)

This BDS 8" lift kit with 4-link conversion raises your 2005-2007 Ford F250/F350 Super Duty gas truck with clearance for up to 38" tires. The 4-link converts the factory stamped steel radius arms to HD upper and lower control arms on 1/4" steel brackets, correcting axle position and limiting caster change through wheel travel for better handling, strength, and stability. Up front it includes gas-specific Pro-Ride coil springs, a forged drop pitman arm and track bar drop bracket for steering correction, sway bar relocation, and brake line brackets. The rear uses replacement Glide-Ride leaf springs with an integrated overload leaf, u-bolts, and brake line brackets. The triple-stage Glide-Ride design keeps ride quality unloaded while engaging the overload leaf for full hauling capacity. Choose NX2 Nitro or FOX 2.0 Performance shocks front and rear.
