BDS Suspension BDS578H - 4 Inch Lift Kit Ford F250/F350 Super Duty 11-16 4WD Gas Block Kit NX2 Nitro

Update the look of your 2011-2016 Ford F250 and F350 Super Duty gas powered truck with this 4-inch 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 inch Tires.

Up front the lift kit includes gas-specific Pro-Ride coil springs, heavy-duty radius arm drop brackets, 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, u-bolt flip kit for max ground clearance, brake line brackets and a matching set of NX2 Nitro or FOX Performance shocks.

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.
