Description
Update the style of your 1999-2004 Ford F250 and F350 Super Duty diesel 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" tires.
Up front the lift kit includes Glide-Ride leaf springs, forged drop pitman arm and track bar bracket for steering correction, sway bar links, bump stop brackets and precision tuned NX2 or FOX nitrogen charged shocks.
In the rear this kit utilizes a high-strength lift block, longer u-bolts and a matching set of NX2 Nitro or FOX Performance shocks.
Glide-Ride Leaf Springs
Built to outperform, BDS engineered the Glide-Ride leaf springs into a multi-leaf progressive spring rate design that provides a smooth ride with any load. This is accomplished with an exclusive triple-stage leaf spring design. Upgrading to BDS Glide-Ride leaf springs will provide flexibility throughout the suspension cycle.
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.

Important fitment notes
- These trucks were manufactured with two different style front u-bolts. You will need to know if your front leaf spring u-bolts are square or are half way between round and square with a gentle radius around the OE cast u-bolt plate before ordering.
- Kits with the Radius front U-bolts do not include swaybar links
- Vehicles produced before 3/1/99 require a different box kit. You must check the production date on the door prior to ordering.
- The Superduty came from the factory with a 2", 3", or 4" rear block. If you wish to truly level your vehicle it may be necessary to change the rear OE block.
- Will not fit dually applications.
- These trucks were produced both with and without a top mounted over load spring. There is an extra leaf that mounts on top of the rear leaf pack. You will need to know how your truck is equipped before ordering.
- If your vehicle is equipped with a carrier bearing, you will want the 123402 drop kit in the accessories section.
Warranty
BDS warranty coverage is for the original retail purchaser with proof of purchase. BDS hard parts and bushings have lifetime replacement coverage; finish and normal wear are excluded.
BDS NX2 and BDS/FOX Performance Series shocks have limited lifetime coverage excluding normal wear and oil seals. At BDS’s discretion, qualifying leaking seals less than two years old may be considered for repair or replacement.
FOX proprietary shocks and coilovers follow FOX warranty terms rather than the BDS warranty. Qualifying leaking seals less than one year old may be considered; other FOX concerns follow the FOX service process.
Properly maintained ball joints and tie-rod ends less than three years old may qualify, subject to the manufacturer’s conditions.
Remedies are repair or replacement at BDS’s discretion. Eligible warranty ground shipping is covered; removal, installation, expedited freight and consequential costs are excluded.
