BDS 4-Inch Lift Kit — Dodge Ram 2500 Power Wagon SKU: BDS1770FS | Dodge Ram 2500 Power Wagon 2009–2013 | 4WD | 4" Front / 4" Rear | FOX 2.0 Performance Series | Leaf Springs Rear

A complete 4-inch suspension lift kit engineered specifically for the 2009–2013 Dodge/Ram 2500 Power Wagon. BDS-engineered lower control arms are longer than stock to rotate the axle for proper alignment, paired with a relocation mounting bracket to flatten the upper control arm angle. Diesel-specific progressive rate Pro-Ride coil springs provide the 4-inch front lift. Forged drop pitman arm and track bar bracket correct steering geometry. The rear uses progressive rate multi-leaf springs for a 4-inch rear lift with extended U-bolts. FOX 2.0 Performance Series shocks front and rear. Clears up to 36-inch tires.

Before ordering: This kit is designed for the Dodge/Ram 2500 Power Wagon only. These vehicles were manufactured with two different diameter rear axles — 3-1/2 inch or 4 inch. Measure your rear axle before ordering. Exhaust modification may be required to clear the front driveshaft at full suspension droop — confirm with your installer before scheduling. Welding equipment and a cut-off wheel are required specialty tools.

The Obsidian Take

The BDS1770FS is the 2009–2013 entry in the BDS Power Wagon lift lineup — same 4-inch front / 4-inch rear format as BDS1764FS and BDS1767FS, leaf spring rear, FOX 2.0 shocks, and an 8-hour Moderate installation. Two diameters exist in the rear axle on this platform — measure before ordering. The conditional exhaust note is worth a conversation with the installer before the job starts.
