Configured for trucks with radius front U-bolts (typically 2001–2004; note sway bar links are not included with radius U-bolt kits) and with a factory rear overload leaf spring. Includes FOX 2.0 Performance Series shocks front and rear — featuring a 2-inch impact extruded aluminum body, internal floating piston (IFP) monotube design, CNC machined 6061-T6 aluminum mounting ends, massive 5/8-inch hard chrome plated heat-treated alloy steel shaft, race-developed high-flow piston design, application-specific valving, and a long-lasting clear anodized finish.
Overview
This 4-inch lift kit from BDS Suspension is designed for 1999–2004 Ford F250 and F350 Super Duty diesel trucks (4WD), providing improved stance, performance, and capability with clearance for up to 35-inch tires. Up front, the kit includes Glide-Ride leaf springs, a forged drop pitman arm, a track bar bracket for steering correction, sway bar links (where applicable), bump stop brackets, and precision-tuned nitrogen-charged shocks. In the rear, the kit utilizes a high-strength lift block, longer U-bolts, and a matching set of rear shocks. Available with NX2 Nitro Series or FOX 2.0 Performance Series shocks.
Glide-Ride Leaf Springs
BDS engineered the Glide-Ride leaf springs into a multi-leaf progressive spring rate design using an exclusive triple-stage construction. This provides a smooth ride under any load and delivers flexibility throughout the full suspension cycle.
Steering Correction
A forged drop pitman arm minimizes steering angle after the lift is installed. Paired with a heavy-duty track bar drop bracket, steering geometry is kept in phase through suspension travel while recentering the front axle.

Important 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 sway bar 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 Super Duty came from the factory with a 2
