Upgrade your 2017-2019 Ford F350 DRW Super Duty gas truck with this BDS 4" lift kit and 4-link conversion, clearing up to 37" tires. Up front it includes gas-specific Pro-Ride coil springs, 4-link control arms with conversion brackets, forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, brake line brackets and nitrogen charged shocks. The rear uses a high-strength fabricated lift block, longer u-bolts, brake line brackets and a matching set of NX2 Nitro or FOX 2.0 Performance shocks. The 4-link conversion replaces the factory stamped steel radius arms to optimize suspension geometry, add strength and limit caster change through wheel travel.
