BDS Suspension 4" Lift Kit w/ Radius Arm

Improve the ride on your 2005-2007 Ford F250 and F350 Super Duty diesel 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 truck up right with clearance for up to 35" tires.

Up front the lift kit includes diesel-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 the base kit utilizes a high-strength lift block, u-bolt flip kit for max ground clearance, 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, diesel-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.
