Important notes before you order
- Measure rear axle tube before ordering. Some 4" axle models with dual overloads will require u-bolt 4068.
- Although unusual, if driveline vibration occurs, order appropriate transfer case drop kit 122602 (03-05 Diesel Auto), 122605 (06-08 Diesel Auto), or 122606 (03-13 Diesel Auto with OE mount P/N 52121938AA) available in options or t-case index kit. #122801 auto or #122802 for manual transmission.
- Optional transfer case drop kits fit automatic transmission models only.
- Exhaust modification will be required for dual rear shock kit 122009 on 6.7L Diesel models.
- If your Truck has had the steering gear box changed and the sector shaft diameter measures ~1-1/2"-1-5/8" you will need to add part # BDS082404 to your kit.
TRU specialist notes
From the Trucks R Us fitment and install team, beyond the manufacturer's information.
- Plan for a professional wheel alignment after installing any lift or leveling kit.
- Going to bigger tires as well? Speedometer recalibration may be needed, and some tire and wheel combinations need trimming. Check the recommended wheels and tires, or ask us before you order.

Overview
Built to outperform, BDS Suspension engineered a 6-inch lift kit with long arm conversion for your 2008 Dodge RAM 2500 and 3500 4WD diesel powered truck that maximizes performance on and off road. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 37" tires. BDS built the long lower control arms to reduce caster change through wheel travel which creates a more controlled feeling in the steering wheel. This long arm long arm system retains the factory triangulation of the arms which adds to the stability of the suspension system.
Up front the lift kit includes diesel-specific Pro-Ride coil springs, all four control arms plus mounting bracket, forged drop pitman arm and track bar bracket for steering correction, bump stops, sway bar links, and precision tuned NX2 or FOX 2.0 nitrogen charged shocks. In the rear this kit utilizes heavy duty cast steel blocks, longer u-bolts, and a matching set of NX2 Nitro or FOX 2.0 Performance shocks.
Pro-Ride Coil Springs
A pair of full-length, diesel-specific, progressive rate Pro-Ride coil springs are supplied to provide the correct lift height and smooth, predictable ride across various terrains. Manufactured from high tensile steel, our direct OE replacement coil springs are engineered with properly sized wire diameter. This results in maximum reliability without premature coil bind.
Steering Correction
To optimize steering geometry once lifted, a forged drop pitman arm is used to minimize the steering angle and pair it with a heavy duty track bar drop bracket to keep them in phase through suspension travel while recentering the front axle.
