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

BDS 6-Inch Lift Kit | FOX 2.0 Performance Series Shocks | Leaf Springs + 4-Inch Axle Block | Ram 2500 4WD Diesel 2009–2013 | SKU: BDS6673FS

The BDS 6-Inch Suspension Lift Kit (SKU: BDS6673FS) is a complete front and rear lift system for 2009–2013 Ram 2500 4WD diesel models. The front system delivers a 6-inch lift using diesel-tuned coil springs and geometry-correct radius arm correction brackets — maintaining proper caster, stabilizing steering, and preserving driveline alignment at lifted height. The rear system uses replacement leaf springs and 4-inch axle blocks to match the front lift height while maintaining load capacity and proper rear stance. The included FOX 2.0 Performance Series shocks provide improved damping control, heat resistance, and ride quality for towing, hauling, and daily use on the diesel platform.

Verified Fitment (OFAS Standard)

• Ram 2500 4WD Diesel: 2009–2013

Does NOT fit: Ram 2500 gas — different front suspension tuning and engine bay configuration. Does not fit Ram 2500 2WD. Does not fit Ram 2500 2014 or newer — different platform and suspension architecture. Does not fit Ram 3500. Does not fit Ram 1500 or Ram 1500 Classic. Confirm model year, drivetrain, and engine before ordering.

Two Critical Fitment Gates

• 4WD only: This kit is engineered for 4WD Ram 2500. Does not fit 2WD models.
• Diesel only: Coil springs and geometry are tuned for the diesel engine platform and its front-end weight distribution. Does not fit gas models — order BDS2101FS for Ram 2500 4WD gas 2014–2018.

Front and Rear Lift System

• Front — 6-inch coil lift: Diesel-tuned coil springs deliver 6 inches of front lift height. Geometry-correct radius arm correction brackets maintain proper caster and driveline alignment at lifted height.
• Rear — Leaf springs + 4-inch axle block: Replacement rear leaf springs and 4-inch axle blocks match the front lift height while maintaining rear load capacity and proper stance. Axle blocks position the axle correctly relative to the leaf spring pack at lifted height.
• Matched system: Front and rear components are engineered together — proper front-to-rear lift ratio, consistent stance, and predictable handling under load.

Geometry Correction — Why It Matters on Diesel

• Diesel front-end weight: Ram 2500 diesel carries significantly more front-end weight than gas models — geometry correction is critical for maintaining caster, steering stability, and driveline alignment under load at 6-inch lift height
• Radius arm correction brackets: Correct the caster angle and radius arm geometry at lifted height — prevents the steering wander, tire wear, and driveline vibration caused by incorrect geometry on lifted diesel trucks
• Track bar correction: Maintains proper axle centering at lifted height

FOX 2.0 Performance Series Shocks

• Improved damping: FOX 2.0 Performance Series shocks deliver significantly improved damping control over factory shocks at lifted height
• Heat resistance: 2.0-inch shock body provides greater oil volume for improved heat dissipation during extended towing and off-road use — critical for diesel work trucks
• Ride quality: Tuned for the Ram 2500 4WD diesel platform — balanced on-road comfort and off-road control
• FOX warranty: FOX 2.0 Performance Series shocks include a 1-year limited warranty

Installation Notes

• Professional installation required: Front and rear suspension lift with geometry correction is a complex modification — professional installation by a qualified suspension shop is required. Incorrect installation can cause handling instability, driveline vibration, component failure, and safety hazards.
• Alignment mandatory: Full front-end alignment is required after installation. Do not drive on public roads before alignment is completed.
• Driveline inspection: At 6-inch lift height, inspect driveshaft angles and U-joint operating angles after installation. Contact OFAS at 903-347-3875 if driveline vibration is present after installation.
• Torque specs: All suspension fasteners must be torqued to BDS specifications per installation instructions.
• Break-in period: Allow FOX shocks and new leaf springs to break in per BDS and FOX recommendations before aggressive off-road use.
• Tire sizing: Contact OFAS at 903-347-3875 to confirm maximum tire size for your Ram 2500 diesel with this 6-inch lift before ordering wheels and tires.

Installation Warning

Professional installation required. Alignment mandatory after installation. Driveline inspection required at 6-inch lift height. Does not fit gas models, 2WD, or 2014 and newer Ram 2500. Does not fit Ram 3500.
