BDS 6-Inch Lift Kit | FOX 2.0 Shocks | Leaf Springs + 4-Inch Axle | Ram 2500 4WD Gas 2009-2013

BDS 6-Inch Lift Kit | FOX 2.0 Performance Series Shocks | Leaf Springs + 4-Inch Axle Block | Ram 2500 4WD Gas 2009–2013 | SKU: BDS677FS

The BDS 6-Inch Suspension Lift Kit (SKU: BDS677FS) is a complete front and rear lift system for 2009–2013 Ram 2500 4WD gas models. This kit uses a 4-inch rear axle block — distinct from BDS676FS which uses a 3.5-inch rear axle block for the same platform. The front system delivers a 6-inch lift using gas-tuned coil springs and geometry-correct radius arm correction brackets. The rear system uses replacement leaf springs and 4-inch axle blocks. The included FOX 2.0 Performance Series shocks provide improved damping control, heat resistance, and ride quality. Contact OFAS at 903-347-3875 to confirm whether BDS677FS (4-inch axle block) or BDS676FS (3.5-inch axle block) is correct for your specific Ram 2500 configuration before ordering.
