BDS 4 Inch Lift Kit w/ 4-Link | Ram 3500 (2019-2024) 4WD Diesel | w/ Rear Overload Leaf | 8-Bolt | FOX 2.0 Performance Series

Configured with factory rear overload leaf, with an 8-bolt indexing ring and FOX 2.0 Performance Series shocks. Select this rear lift option if your RAM 3500 is equipped with the factory rear overload leaf spring. The 8-bolt indexing ring kit is required for trucks equipped with the optional Aisin heavy-duty 6-speed transmission; it includes an internal shaft seal extension and new shaft seal. The FOX 2.0 Performance Series features a 2-inch impact extruded aluminum body, an internal floating piston (IFP) monotube design, a 5/8-inch hard chrome plated heat-treated alloy steel shaft, CNC machined 6061-T6 aluminum mounting ends, and application-specific valving.

Overview

BDS Suspension engineered this 4-inch lift kit with 4-link conversion for the 2019–2024 RAM 3500 4WD diesel-powered truck. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up with clearance for up to 37-inch tires.

Up front, the kit includes diesel-specific Pro-Ride coil springs, heavy-duty replacement radius arms, a forged drop pitman arm, a track bar bracket for steering correction, sway bar relocation, and brake line brackets. At this lift height, the transfer case is indexed to allow use of the factory front driveshaft; an indexing ring and new transmission crossmember are included. In the rear, the kit utilizes a high-strength fabricated lift block, longer U-bolts, and a matched set of rear shocks.

4-Link Conversion

The BDS 4-link conversion replaces the factory stamped steel radius arms to optimize suspension geometry for improved handling characteristics while adding strength and stability. This bolt-on upgrade uses high-strength 1/4-inch steel brackets to mount HD upper and lower control arms, correcting axle positioning and limiting caster change throughout wheel travel.

Pro-Ride Coil Springs

A pair of full-length, dual-rate Pro-Ride coil springs provide the correct lift height and smooth, predictable ride across various terrains.

Steering Correction

A forged drop pitman arm minimizes steering angle once lifted, paired with a heavy-duty track bar drop bracket to keep the steering geometry in phase through suspension travel while recentering the front axle.
