4 Inch Lift Kit w/ 4-Link | Ram 3500 (2013-2018) 4WD Diesel | 3 Inch Block Kit | FOX 2.0 Performance Series | BDS Suspension

Configured with a 3 Inch Block Kit for a slightly tail-high rear stance, paired with FOX 2.0 Performance Series shocks featuring a 2-inch impact extruded aluminum body, internal floating piston (IFP) monotube design, massive 5/8-inch hard chrome plated heat-treated alloy steel shaft, CNC machined 6061-T6 aluminum mounting ends, and application-specific valving with a clear anodized finish.

Overview

BDS Suspension engineered this 4-inch lift kit with 4-Link conversion for the 2013–2018 RAM 3500 diesel-powered truck. Designed to improve stance, performance, and capability, this kit includes everything necessary to set the truck up with clearance for up to 35-inch tires. Up front, the kit includes diesel-specific Pro-Ride coil springs, 4-Link control arms with conversion mounts, a forged drop pitman arm, track bar bracket for steering correction, bump stops, and brake line brackets. In the rear, the kit utilizes a high-strength fabricated lift block and longer U-bolts. Shocks are included front and rear in the selected configuration.

4-Link Conversion

The 4-Link conversion replaces the factory stamped steel radius arms to optimize suspension geometry for improved handling characteristics, strength, and stability. This bolt-on upgrade uses 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 provide the correct lift height and smooth, predictable ride across various terrains.

Steering Correction

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