BDS 6-Inch Lift Kit | FOX 2.0 Shocks | Leaf Springs + 3.5-Inch Axle Block | Ram 2500 4WD Gas 2009–2013 | SKU: 676FS

The BDS 676FS is a 6-inch lift kit with FOX 2.0 Performance Series shocks for the 2009–2013 Ram 2500 4WD gas. Front lift is delivered via gas-tuned coil springs and geometry-correct radius arm correction brackets. Rear lift is matched via replacement leaf springs and 3.5-inch axle blocks. The complete front-to-rear system is engineered for the 2009–2013 Ram 2500 gas platform — gas engine weight, gas spring tuning, correct geometry throughout.

Before ordering — confirm the axle block height for your configuration. There are two 6-inch kits for the 2009–2013 Ram 2500 gas: 676FS uses a 3.5-inch rear axle block and 677FS uses a 4-inch rear axle block. The correct axle block height depends on your cab style and configuration. Text (469) 407-7538 to confirm which is correct before ordering.

This kit has three additional hard fitment splits before it applies to your truck.

First — engine: the front coil springs in this kit are gas-tuned. Ram 2500 diesel requires a different kit — order 6673FS for 2009–2013 Ram 2500 diesel.

Second — year: 2009–2013 only. The 2008 and earlier Ram 2500 uses a different platform. The 2014 and newer Ram 2500 uses a different platform.

Third — drivetrain: 4WD only. Ram 2500 2WD is not compatible.

Tire Clearance

At 6 inches of lift on the 2009–2013 Ram 2500 gas platform, typical fitment runs 37–40-inch tires depending on wheel offset and backspacing. Confirm maximum tire diameter and wheel specifications with your wheel and tire supplier before ordering.

Installation Notes

Professional installation is required. A 6-inch lift with leaf spring replacement requires a qualified suspension shop with experience on heavy-duty truck platforms. This is not a bolt-on leveling kit. Do not attempt DIY installation.

Full front-end alignment is mandatory after installation. Do not drive on public roads before alignment is completed. Running a lifted truck without post-installation alignment causes accelerated tire wear, steering pull, and handling instability.

Driveline inspection is required at 6-inch lift. At 6 inches, inspect driveshaft angles and U-joint operating angles after installation. Driveshaft modification may be required depending on your specific configuration — confirm with your installer before the job begins.

Rear axle block installation. 3.5-inch axle blocks must be installed per BDS specifications. Confirm U-bolt torque specs and axle centering after installation — improperly centered axle blocks cause driveline vibration and premature U-joint wear.

Torque all fasteners to BDS specification. Torque specs are included in the BDS installation instructions. Do not estimate torque values.

FOX shock break-in period. Allow FOX 2.0 shocks to complete the manufacturer-recommended break-in period before aggressive off-road or heavy towing use.

The Obsidian Take

The BDS 676FS is the correct kit for the 2009–2013 Ram 2500 4WD gas owner who wants 6 inches of front and matched rear lift with FOX 2.0 damping and a 3.5-inch rear axle block. Gas-tuned springs front, replacement leaf springs and 3.5-inch axle blocks rear, geometry-correct radius arm brackets throughout — a complete front-to-rear system tuned for the gas engine weight and load demands of this platform.

The only variable between this kit and 677FS is the rear axle block height — 3.5 inches here, 4 inches there. That difference determines rear ride height and geometry balance for your specific cab and configuration. Ordering the wrong axle block height is the most common misorder on this platform and the kit is non-returnable once installed. Text (469) 407-7538 with your cab style and configuration before the order ships.

If your Ram 2500 is diesel, this is the wrong kit — the gas-tuned springs are not correct for the diesel engine weight. Order 6673FS. If your Ram 2500 is a 2008 or earlier or 2014 or newer, this kit does not apply — different platform, different geometry. If you have a Ram 3500 on this platform, confirm compatibility before ordering.

2009–2013, gas, 4WD, 3.5-inch axle block confirmed — the 676FS is the complete, platform-correct solution.

Common Questions

What is the difference between 676FS and 677FS?
Both kits fit the 2009–2013 Ram 2500 4WD gas and deliver 6 inches of front lift. The only difference is the rear axle block height — 676FS uses a 3.5-inch block and 677FS uses a 4-inch block. Text (469) 407-7538 to confirm which is correct for your cab style and configuration before ordering.

Why does it matter if my Ram 2500 is gas or diesel?
The front coil springs in this kit are tuned for the gas engine weight. The diesel engine is significantly heavier — diesel-tuned springs are required for the correct front ride height, geometry, and load handling on a diesel platform. Order 6673FS for the 2009–2013 Ram 2500 diesel.

Does this fit my Ram 3500?
Ram 3500 compatibility on the 2009–2013 gas platform is not confirmed for this kit. Text (469) 407-7538 with your Ram 3500 year, engine, and drivetrain before ordering.

What is the driveline inspection for and can I skip it?
At 6 inches of lift, driveshaft angles change significantly from factory. U-joints operating outside their designed angle range wear rapidly and can fail under load. The inspection confirms whether your driveshaft requires modification — it is not optional at this lift height.

What tire size fits at 6-inch lift?
Typical fitment on the 2009–2013 Ram 2500 gas at 6-inch lift runs 37–40-inch tires depending on wheel offset and backspacing. Confirm maximum tire diameter and wheel specs with your wheel and tire supplier before ordering.

What warranty does this kit carry?
BDS suspension components carry the BDS No-Fine-Print Warranty. FOX 2.0 shocks carry a FOX 1-year limited warranty.
