Configured with BDS Leaf Springs for the rear — providing a 5-inch rear lift with included u-bolts. Eliminates the need for a lift block, reduces axle wrap, and delivers a more controlled and stable feel. Multi-leaf progressive design maintains factory payload weight ratings. Sized for a 3-1/2 inch diameter rear axle.
Equipped with FOX 2.0 Performance Series shocks featuring a 2-inch impact extruded aluminum body, internal floating piston (IFP) monotube design, CNC machined 6061-T6 aluminum mounting ends, a massive 5/8-inch hard chrome plated heat-treated alloy steel shaft, race-developed high-flow piston, application-specific valving, and a long-lasting clear anodized finish.
Overview
This 4-inch lift kit from BDS Suspension is designed for the 2005–2007 Dodge Ram 2500 Power Wagon 4WD, improving stance, performance, and capability with clearance for up to 36-inch tires. BDS engineered new lower control arms are longer than stock to rotate the axle for proper alignment, and a relocation mounting bracket is included to flatten the upper control arm angle and maintain factory handling characteristics. Up front, the kit includes gas-specific Pro-Ride coil springs, all four control arms plus relocation bracket, a forged drop pitman arm, a track bar bracket for steering correction, bump stops, sway bar links, and precision-tuned shocks. The rear configuration varies by selected option — see variant details for rear lift and axle specifics.

Important Notes
- These vehicles were manufactured with two different diameter rear axles. Measure the diameter of your rear axle before ordering — it should be 3-1/2 inches or 4 inches in diameter.
- May require exhaust modification to clear the front driveshaft at full droop.
- If your truck has had the steering gear box changed and the sector shaft diameter measures approximately 1-1/2 inches to 1-5/8 inches, you will need to add part #BDS082404 to your kit.
