BDS SUSPENSION BDS311H 6 INCH LIFT KIT FORD F250/F350 SUPER DUTY 99-04 4WD SQUARE PRIOR TO 2-28-99 LEAF SPRINGS W/ NX2 NITRO SHOCKS

Take your 1999-2004 Ford F250 and F350 Super Duty truck to the next level with 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 36 inch 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 the base kit utilizes a high-strength lift block, longer u-bolts and a matching set of NX2 Nitro or FOX Performance shocks. Optional replacement full leaf spring packs for an improved ride on or off-road.

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.

Features & Benefits

Front U-Bolt Type

• Square U Bolt Prior to 2-28-99

This vehicle was manufactured with either square front U-Bolts or radiused front U-bolts. Typically, 1999-2000 are square and 2001-2004 are radiused, but that is not always the case.

The radiused U-bolts aren't square or round, but rather have a gentle radius that matches a cast factory upper U-bolt plate on top of the factory spring. Vehicles manufactured prior to 2-28-99 require yet another different box kit due to a change in the factory track bar.
