  • $2,633.12

BDS Suspension is now shipping suspension lifts and accessories for the rear air ride equipped RAM 3500 4WD trucks.
These lift systems are designed to convert the factory radius arm over to a stronger 4-link design offering improved stability, handling and articulation. The kit is designed with 1/4" fabricated 4-link brackets that key into the factory radius arm pockets for added strength. The 4-link design improves handling and drivability by limiting castor change to less than 1-degree throughout wheel travel. These kits also include 6" diesel engine specific progressive rate front ProRide coil springs, a heavy duty front track bar bracket, forged drop pitman arm, extended bump stops, brake line relocation brackets, sway bar correction, high clearance transmission crossmember and transfer case indexing ring, rear block and u-bolt kit along with rear air bag lower spacers and sensor brackets. All kits are finished off with your choice of BDS NX2 or FOX 2.0 gas shocks at all 4 corners. These kits allow for up to 37" tires to be installed.

No Fine Print Warranty
BDS stands behind its products and that’s evident by their No Fine Print Warranty. This no-BS warranty protects the original purchaser against breakage, bending, sagging, or any other usage failure. This “no fine print” lifetime replacement warranty extends to cover all BDS hard parts as well as bushings. Exclusions would be product finish and wearable items such as shock/stabilizer cylinders, tie rod ends and ball joints that would fall under the separate Limited Lifetime Warranty policy. Beginning February 1, 2020 all new kit purchases include the No Fine Print Warranty on bushings.

Limited Lifetime Warranty (for wearable items)
Wearable items include shock/steering stabilizer cylinders, ball joints and tie rod ends. BDS Suspension Co. warrants to the original retail purchaser that its these wearable parts are free from defects in material and workmanship for so long as they own the vehicle. Excluded from this warranty are the finish of the product. Defects in material and workmanship do not include such things as dented cylinders or bent rods caused by obvious side impact, rust or corrosion. 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.
