Important Notes
- Carrier bearing drop kit will be required for 2-piece rear drive shaft
- Some vehicles may require a rear driveshaft spacer kit to maintain adequate rear driveshaft engagement
- 40x13.50 tires may require some trimming, and depending on wheel width and backspacing may require spacing the front bumper forward and inner fender trimming.
Features & Benefits
- Heavy duty 4-link arms improve strength, handling and caster control
- High strength progressive rate coil springs for a great ride on any terrain
- Track bar relocation brackets to re-position axle
- Forged drop pitman arm to correct steering angles
- Front sway bar correction to maintain handling performance
- HD transmission crossmember and t-case indexing ring to correct front driveline angles and allow use of factory driveshafts
- BDS NX2 gas or FOX performance series IFP gas shocks to improved ride and offroad performance
Go big with the BDS Suspension engineered 8-inch lift kit with 4-Link conversion for your 2014-2018 RAM 2500 diesel powered truck. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 40" tires.
Up front the lift kit includes diesel-specific Pro-Ride coil springs, 4-Link control arms with conversion mounts, forged drop pitman arm and track bar bracket for steering correction, bump stops, brake line brackets and precision tuned NX2 or FOX 2.0 nitrogen charged shocks. At this height, the transfer case needs to be indexed to allow use of the factory front driveshaft so an indexing ring and new transmission crossmember are supplied.
In the rear, careful consideration was taken to design the system for load carrying capacity, handling, and ride quality. To do this, BDS engineered new coil bucket seats to mount them outboard the frame rail similar to a leaf spring style truck. The new upper and lower coil seats require only minor drilling for mounting hardware. The new position allows for a much shorter and more stable coil spring design. This virtually eliminates any chance of coil bowing and ensures the coils react predictably throughout the full range of travel.
In addition to the coil springs/mounts, a new track bar relocation system is included to properly set the rear roll-center height and center the axle under the vehicle. The rear track bar relocation includes a new heavy duty adjustable track bar. Finishing out the rear this kit utilizes extended sway bar links and a matching set of NX2 Nitro or FOX 2.0 Performance shocks.
4-Link Conversion
Convert the factory stamped steel radius arms over to the BDS 4-link to optimize suspension geometry for better handling characteristics while adding strength and stability. This bolt-on upgrade utilizes high-strength 1/4-inch steel brackets that allow mounting of 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 supplied to provide the correct lift height and smooth, predictable ride across various terrains. Manufactured from high tensile steel, our direct OE replacement coil springs are engineered with properly sized wire diameter. This results in maximum reliability without premature coil bind.
Steering Correction
To optimize steering geometry once lifted, a forged drop pitman arm is used to minimize the steering angle and pair it with a heavy duty track bar drop bracket to keep them in phase through suspension travel while recentering the front axle.
