Ultimate Bds 1671fs 4 Inch 4-link Lift Kit With Fox 2.0 Shocks | 2019-2024 Ram 3500 6.7l Cummins 4wd Unlock 55% Savings [FqmhSHCf]

Features & Benefits

  • Rear Lift Option: With Factory Rear Overload Leaf
  • Heavy duty 4-link improve strength, handling and caster control
  • Front high strength progressive rate coil springs for a great ride on any terrain
  • Front track bar relocation bracket 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
  • FOX performance series IFP gas shocks to improved ride and offroad performance
Built to outperform, BDS Suspension engineered a 4-inch lift kit with 4-Link conversion for your RAM 3500 diesel powered truck that will surely impress. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 35" tires.

Up front the lift kit includes diesel-specific Pro-Ride coil springs, heavy-duty replacement radius arms, forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, brake line brackets and precision tuned 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 this kit utilizes a high-strength fabricated lift block, longer u-bolts and a matching set of 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.

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.
