Configured for trucks without factory rear overload leaf springs, with a 6-bolt transfer case indexing ring kit, and NX2 Nitro Series shocks. NX2 shocks feature a nitrogen-charged twin-tube design, 10-stage velocity-sensitive valving, dual-welded ends, a 1-3/8-inch high-flow piston, self-lubricating seals, and a silver powder coat finish.
Overview
This 8-inch 4-Link lift kit from BDS Suspension is engineered for the 2019–2024 Ram 3500 4WD diesel truck, providing increased stance, performance, and off-road capability with clearance for up to 40-inch tires. Up front, the kit includes diesel-specific Pro-Ride coil springs, a 4-link control arm conversion, a forged drop pitman arm, a track bar bracket for steering correction, sway bar relocation hardware, brake line brackets, and custom-tuned nitrogen charged shocks. A transfer case indexing ring with ARP studs and a new high-clearance transmission crossmember are supplied to allow use of the factory front driveshaft at this lift height. At the rear, the kit uses heavy duty steel lift blocks, add-a-leaf springs, u-bolts, and a matched set of shocks.
The 4-Link conversion replaces the factory stamped steel radius arms with high-strength 1/4-inch steel brackets supporting HD upper and lower control arms, correcting axle positioning and limiting caster change throughout wheel travel. Diesel-specific Pro-Ride coil springs deliver the correct lift height and a smooth, predictable ride across various terrains. The precision-built transfer case indexing ring clocks the transfer case to improve the front driveline operating angle.

Important Notes
- Does not fit OE equipped air ride systems.
- Recoil Traction Bars Recommended.
- Dually with 8-bolt Transmission (Aisin) requires BDS122409 DEF Relocation Kit.
- Mega Cabs with 8-bolt Transmission (Aisin) require BDS122409 DEF Relocation Kit.
- Vehicles equipped with a Manual T-case require BDS122423 Manual Transfer Case Shifter Extension.
- Vehicles equipped with a 2-piece rear drive shaft (carrier bearing) require BDS122406 Carrier Bearing Drop.
- This kit requires the use of an aftermarket front driveshaft (not provided) in addition to the provided indexing ring kit BDS122624 (6-bolt) or BDS122421 (8-bolt). Both must be installed; however, due to variations between truck configurations, BDS recommends installing the kit prior to taking measurements for the aftermarket front driveshaft to ensure correct length. The vehicle can be driven without the front driveshaft during this process.
- Kit was tested with a Drive Line Plus flange and driveshaft; other high-angle driveshaft options can be used.
