Description

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 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 this kit utilizes a high-strength fabricated lift block, heavy duty air bag spacers, longer u-bolts 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.

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.

Warranty

BDS warranty coverage is for the original retail purchaser with proof of purchase. BDS hard parts and bushings have lifetime replacement coverage; finish and normal wear are excluded.

BDS NX2 and BDS/FOX Performance Series shocks have limited lifetime coverage excluding normal wear and oil seals. At BDS’s discretion, qualifying leaking seals less than two years old may be considered for repair or replacement.

FOX proprietary shocks and coilovers follow FOX warranty terms rather than the BDS warranty. Qualifying leaking seals less than one year old may be considered; other FOX concerns follow the FOX service process.

Properly maintained ball joints and tie-rod ends less than three years old may qualify, subject to the manufacturer’s conditions.

Remedies are repair or replacement at BDS’s discretion. Eligible warranty ground shipping is covered; removal, installation, expedited freight and consequential costs are excluded.

Read the official BDS warranty and FOX service terms.
