Important Notes
- These trucks were manufactured with and without top mounted overload springs on the rear leaf springs. A top mounted overload is an extra leaf separate from the pack that set above the main leaf. You will need to identify which you have before ordering.
- If your vehicle is equipped with a carrier bearing, you will need to order 123402 in the options section.
- Do not install the 4" rear block kit on vehicles equipped with a factory 3-7/8" rear block. Only use rear spring option on these vehicles.

Upgrade your 2005-2007 Ford Super Duty F250 and F350 gas truck and install this 6-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 37" 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 custom-tuned nitrogen charged shocks.
In the rear the base kit utilizes high strength lift blocks, longer u-bolts, 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.
