Configured for trucks without factory rear overload leaf springs, with a 6-bolt indexing ring and NX2 Nitro Series shocks. The NX2 Nitro Series features a nitrogen-charged twin-tube design, 10-stage velocity-sensitive valving, dual-welded ends for increased strength, a 1-3/8-inch high-flow piston, self-lubricating seals, and a silver powder coat finish. The standard 6-bolt indexing ring kit is compatible with the factory Ram 3500 transfer case bolt pattern.
Overview
This 6-inch lift kit with 4-Link conversion from BDS Suspension is designed for 2019–2024 Ram 3500 4WD diesel trucks, providing increased ground clearance with fitment for up to 37-inch tires. Up front, the kit includes diesel-specific Pro-Ride coil springs, a 4-Link control arm conversion, forged drop pitman arm, track bar bracket for steering correction, sway bar relocation, and brake line brackets. A transfer case indexing ring and new HD transmission crossmember are included to allow use of the factory front driveshaft at ride height. The rear utilizes a high-strength steel lift block, longer U-bolts, and matched rear shocks. Shocks are available in NX2 Nitro Series, FOX 2.0 Performance Series, or FOX 2.5 Performance Elite configurations.
4-Link Conversion
The factory stamped steel radius arms are replaced by the BDS 4-Link system to optimize suspension geometry for improved handling, strength, and stability. This bolt-on upgrade uses high-strength 1/4-inch steel brackets that mount HD upper and lower control arms to correct axle positioning while limiting caster change throughout wheel travel.
Pro-Ride Coil Springs
A pair of full-length, diesel-specific, progressive rate Pro-Ride coil springs are included to provide the correct lift height and a smooth, predictable ride across various terrains.
Steering Correction
A forged drop pitman arm minimizes steering angle after the lift is installed. A heavy-duty track bar drop bracket keeps the steering geometry in phase through suspension travel while recentering the front axle.
