BDS 6-Inch Lift Kit | FOX 2.0 Shocks | Leaf Springs + 3.5-Inch Axle Block | Ram 2500/3500 4WD Diesel 2008 Only | SKU: 680FS

Is This for You?

This kit is for the 2008 Ram 2500 or Ram 3500 SRW 4WD diesel owner who wants 6 inches of lift with a 3.5-inch rear axle block. This kit covers 2008 only — not 2007 or earlier, not 2009 or newer. There are two 2008 diesel 6-inch kits: SKU 680FS (3.5-inch axle block, this listing) and SKU 681FS (4-inch axle block). Confirm which axle block height is correct for your cab style and configuration before ordering. If your Ram 2500/3500 is gas, stop here — order SKU 686FS or 687FS for 2008 gas.

The Result

6 inches of front lift via diesel-tuned coil springs and geometry-correct radius arm correction brackets, with matched rear lift via replacement leaf springs and a 3.5-inch axle block — engineered specifically for the 2008 Ram HD diesel platform. The truck clears larger tires, sits aggressive, and maintains consistent geometry under diesel towing loads. FOX 2.0 shocks deliver improved damping over factory at this lift height.

Installation & Fabrication Notes

• Professional installation required: 6-inch lift with leaf spring replacement on a diesel platform requires a qualified suspension shop.
• Alignment mandatory: Full front-end alignment required after installation. Do not drive on public roads before alignment is completed.
• Rear block installation: 3.5-inch axle blocks must be installed per BDS specifications — confirm U-bolt torque specs and axle centering after installation.
• Driveline inspection mandatory: At 6-inch lift, inspect driveshaft angles and U-joint operating angles after installation.
• Torque specs: Torque all fasteners to BDS specification per included installation instructions. Do not estimate.

Wheel & Tire Fitment

At 6-inch lift on the Ram 2500/3500 diesel platform, typical fitment runs 37–40-inch tires depending on wheel offset and backspacing. Confirm maximum tire diameter and wheel specs with your wheel/tire supplier before ordering.

Installation Warning

Application-specific. Confirm 2008 Ram 2500/3500 SRW 4WD diesel before ordering. Confirm 3.5-inch axle block is correct for your configuration — if unsure, contact OFAS before ordering. Does not fit gas, 2WD, 2007 or earlier, or 2009 or newer. Ram 3500 DRW — confirm with OFAS. This product is non-returnable once installed.

Is your Ram 2500 or 3500 exactly a 2008 4WD diesel? Do you need the 3.5-inch axle block (this kit, SKU 680FS) or the 4-inch axle block (SKU 681FS)? Diesel or gas? Submit your year, model, engine, drivetrain, and cab style via the contact form and we’ll confirm the correct SKU before it ships.
