BDS 8 Inch Lift Kit | Long Arm & FOX 2.5 Coil-Over Conversion | 2008 Dodge Ram 2500/3500 4WD Diesel | Block Kit Rear

This configuration includes a Block Kit rear lift option. Rear lift blocks are cast iron for strength, tapered for correct pinion angle, with an offset steel pin and hole to restore axle position. This design eliminates the need for an additional lift block, reduces axle wrap, and creates a more controlled and stable feel while maintaining factory payload weight ratings.

Overview

This 8-inch lift kit with long arm and FOX 2.5 coil-over conversion from BDS Suspension is designed for the 2008 Dodge RAM 2500 and 3500 4WD diesel truck. The kit features proprietary FOX 2.5 coil-over shocks engineered specifically to bolt on for increased travel and the ability to handle rough terrain while maintaining smooth on-road comfort. The kit provides clearance for up to 38-inch tires and includes a mounting system that bolts directly to the factory coil mounts with only minor trimming and drilling required. Weld-in reinforcements at the axle are included for superior strength. The long lower control arms are built to reduce caster change through wheel travel for a more controlled steering feel. The long arm system retains the factory triangulation of the arms, contributing to overall suspension stability.

Up front, the kit includes FOX 2.5 coil-over shocks, all four control arms with mounting brackets, a forged drop pitman arm, a track bar bracket for steering correction, bump stops, and sway bar links. In the rear, the kit utilizes heavy duty cast steel blocks, longer u-bolts, and FOX 2.0 Performance shocks.

FOX 2.5 Coil-Overs

FOX 2.5 coil-overs are tuned and ready to install out of the box. These 2.5-inch diameter bolt-on coil-overs include a remote reservoir for additional fluid capacity to keep shocks running cool during demanding off-road use.

Long Arm Conversion

The long arm conversion consists of massive 1/4-inch steel frame-mounted brackets paired with oversized upper and lower formed long arms. The arms are formed for maximum tire clearance and allow the stock control arm tabs to remain on the vehicle. The upper arms are solid stock while the heavy wall tubular lower arms use oversized greaseable polyurethane bushings for superior road vibration isolation.

Important Notes

• Measure rear axle tube before ordering. Some 4-inch axle models with dual overloads will require UBT4068.
• Rear lift options will not fit dually applications.
• If driveline vibration occurs, order either transfer case drop. NOTE: 122606 transfer case drop kit will only replace the OE bracket #52121938AA.
• Additional front driveline modification may be required.
• Exhaust modification will be required for dual rear shock kit 122009.
• 2500 Gas models will require modification to the front exhaust crossover pipe on the driver side for proper clearance when a transfer case indexing ring kit is installed.
• If your truck has had the steering gear box changed and the sector shaft diameter measures approximately 1-1/2" to 1-5/8", you will need to add part #BDS082404 to your kit.
