2003-2007 Cummins 6" Coilover Lift Kit (BDS647F)
Completely revamp your Cummins front suspension into this 6" upgraded, up-rated Coilover lift system utilizing high-performance Fox 2.5 Coilovers and BDS long arm suspension systems to create the ultimate suspension system that will give you a 6" lift right out the box. Preset to achieve an amazing ride on and off-road, this kit has a mounting system that bolts directly to the factory coil mounts with only minor trimming/drilling required. This new system not only creates a sturdy mount at the frame but also includes weld in reinforcements at the axle - something other "bolt-on" mounting kits on the market does not address.
Tire & Wheel Combinations:
- 37" x 12.50" w/ 17 x 9 and 5"
Notes:
- This truck is available with two different axle sizes, 3.5" or 4". Measure rear axle tube before ordering. Some 4" axle models with dual overloads will require u-bolt 406
- Will not fit dually applications.
- Although unusual, if driveline vibration occurs, order a transfer case drop kit available in options or t-case index kit. #122801 is included in 8" kits, substitute #122802 for manual transmission.
- Exhaust modification will be required for dual rear shock kit 122009 on 6.7L Diesel models.
