6" Performance Coilover Lift Kit (FOX 2.0 Shocks) - 2003-2007 Dodge / Ram 2500 / 3500 4WD Diesel

Part # 647F

BDS Performance Series Systems feature Fox 2.5 Reservoir Coilovers. These systems were designed specifically to combine the high-performance characteristics of the Fox 2.5 coilovers and BDS long arm suspension systems to create the ultimate 6" suspension system. The Fox coilovers are preset to achieve 6" of lift right out of the box and tuned for an amazing ride on and off road. In order to install the coilovers, we have developed 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, it also includes weld in reinforcements at the axle - something other "bolt-on" mounting kits on the market do not address. The coilovers along with the mounting system can be purchased separately to retrofit any previously install BDS 6" long arm system.

The rear of the Dodge Ram can be lifted with your choice of a 5" block kit or full replacement rear Glide Ride leaf springs.

  • 2. Will not fit dually applications.
  • 3. Although unusual, if driveline vibration occurs, order transfer case drop kit available in options or t-case index kit. #122801 is included in 8" kits, substitute #122802 for manual transmission.
  • 5. Exhaust modification will be required for dual rear shock kit 122009 on 6.7L Diesel models.
  • 6. 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.

BDS Suspension - "No Fine Print Warranty"

BDS stands behind its products and that's evident by their No Fine Print Warranty. This warranty protects the original retail purchaser against breakage, bending, sagging, or any other usage failure. We don't care if you jumped your truck off a cliff, lit it on fire, rolled it down a hill, installed Chevy parts on your Ford, or even if you didn't read the instructions and cross threaded a bolt with too many Ugga Duggas! This "no fine print" lifetime replacement warranty extends to cover all BDS hard parts and includes a lifetime warranty on bushings! Exclusions would be product finish and wearable items as described below. All warranties require the customer to provide a Proof of purchase including Name, product, purchase date and price paid.

No Fine Print Warranty ~ If you are the original purchaser of any BDS product and it breaks, they will give you a new part. Period.


Wearable Parts | Limited Lifetime Warranty

BDS NX2 Series Shocks and BDS/Fox Performance Series Shocks:
Shock oil seals are not covered by this Limited Lifetime Warranty because they are subject to wear over time and use. At BDS's discretion, leaking shock seals less than 2 years from date of purchase, free from contamination, damage, or abnormal seal wear due to misuse can be considered for repair or replacement under warranty. A shock absorber is a wear item and over time will experience diminished damping resistance due to normal component wear. This is not a defect in material or workmanship and is therefore not warrantable. Defects in material and workmanship do not include such things as dented cylinders or bent rods caused by obvious side impact, rust or corrosion.

Fox Proprietary Shocks and Coil Overs:
Fox Proprietary parts are covered by their warranty and are not included in the BDS Warranty. BDS may offer to assist with the warranty of defective product, at our discretion. Other warranty concerns should be handled through the Fox Service program. Leaking shock seals less than 1 year from date of purchase, free from contamination, damage, or abnormal seal wear due to misuse can be considered for Warranty. FOX service information can be

Ball Joints and Tie Rod Ends:
These items are subject to normal wear over time. However, Ball Joints and Tie Rod ends less than 3 years from the date of purchase, that have been properly greased, maintained, and do not show signs of abnormal use can be considered for warranty.

BDS Suspension's obligation under all warranties is limited to the repair or replacement, at BDS's option, of the defective material. BDS will cover the cost of ground shipping on warranty items, and a return shipping label if we require the warranty part to be returned to us. Any cost of removal, installation or reinstallation, expedited freight charges, incidental or consequential damages are expressly excluded from these warranties. Proof of purchase is required for all warranty claims.
