Improve the ride on your 2017-2019 Ford F350 Dually inchDRW inch Super Duty gas truck with this 4-inch radius arm lift kit from BDS Suspension. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your dually truck up right with clearance for up to 37 inch Tires.
Up front the lift kit includes gas-specific Pro-Ride coil springs, heavy-duty replacement radius arms, forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, brake line brackets and precision tuned nitrogen charged shocks.
In the rear this kit utilizes a high-strength fabricated lift block, longer u-bolts, brake line brackets and a matching set of NX2 Nitro or FOX Performance shocks.
HD Radius Arms
In place of the factory stamped steel radius arms BDS supplies a pair of high-strength tubular radius arms. These arms mount into the factory location and offer caster adjustment for a wide range of lift heights along with an OE-style rubber bushing at the frame mount for smooth, quiet, service-free operation.
Pro-Ride Coil Springs
A pair of full-length, gas-specific, Pro-Ride coil springs are supplied to provide the correct lift height and smooth, predictable ride across various terrains.
Steering Correction
To optimize steering geometry once lifted, a forged drop pitman arm is used to minimize the steering angle and pair it with a heavy duty track bar drop bracket to keep them in phase through suspension travel while recentering the front axle.
