BDS 6-Inch Lift Kit | FOX 2.0 Shocks | Leaf Springs + 3.5-Inch Axle | Ram 2500/3500 4WD Diesel 2008 Only

BDS 6-Inch Lift Kit | FOX 2.0 Performance Series Shocks | Leaf Springs + 3.5-Inch Axle Block | Ram 2500/3500 4WD Diesel 2008 Only | SKU: BDS680FS

The BDS 6-Inch Suspension Lift Kit (SKU: BDS680FS) is a complete front and rear lift system for 2008 Ram 2500 and Ram 3500 4WD diesel models only. The 2008 Ram HD is a transition year with unique suspension specifications — BDS engineers a dedicated kit for 2008 alone. This kit does not fit 2007 or earlier, and does not fit 2009 or later. The front system delivers a 6-inch lift using diesel-tuned coil springs and geometry-correct radius arm correction brackets. The rear system uses replacement leaf springs and 3.5-inch axle blocks. The included FOX 2.0 Performance Series shocks provide improved damping control, heat resistance, and ride quality for towing, hauling, and daily use.

Verified Fitment (OFAS Standard)

• Ram 2500 4WD Diesel: 2008 only
• Ram 3500 4WD Diesel SRW (Single Rear Wheel): 2008 only

Does NOT fit: Ram 2500 or Ram 3500 2007 or earlier — order BDS236FS (3.5-inch axle) or BDS266FS (4-inch axle) for 2003–2007. Does not fit Ram 2500 or Ram 3500 2009 or newer — order BDS6673FS for 2009–2013 Ram 2500 diesel. Does not fit gas models. Does not fit 2WD models. Ram 3500 DRW (Dually) — contact OFAS at 903-347-3875 to confirm DRW compatibility. Confirm model year is exactly 2008 before ordering.

Why 2008 Requires Its Own Kit

The 2008 Ram 2500/3500 is a transition year between the 2003–2007 and 2009–2013 generations. The 2008 model year has unique front suspension geometry, coil spring specifications, and radius arm bracket requirements that differ from both the 2003–2007 and 2009–2013 platforms. BDS engineers a dedicated kit for 2008 to ensure correct geometry, caster, and driveline alignment at lifted height. Using a 2003–2007 or 2009–2013 kit on a 2008 Ram HD will result in incorrect geometry and potential handling and safety issues.
