6" 2013-2018 Dodge Ram 3500 4WD (w/diesel engine) Fox 2.5 Performance Elite Coilover / 4-Link Lift Kit by BDS Suspension

Take your RAM 3500 to the next level with the BDS 1782PES / 2133PES 6" 4-Link Coilover Lift Kit. Designed for drivers who demand performance and durability, this system replaces the factory suspension with heavy-duty 4-Link arms, precision coilovers, and premium shocks for ultimate control on and off the road. Whether you’re crawling rocky trails, hauling heavy loads, or cruising in town, this kit delivers strength, stability, and a commanding stance.

Coilover Conversion with FOX Performance Elite

The front suspension is upgraded with the BDS Coilover Conversion Kit, which mounts directly into the factory coil spring buckets. Outfitted with FOX 2.5 Performance Elite coilovers with DSC (Dual Speed Compression) adjusters, this setup allows you to fine-tune low-speed and high-speed compression independently. That means plush comfort for daily driving and precise damping control when the terrain gets rough.

In the rear, matching FOX 2.5 Performance Elite shocks with DSC adjusters keep your truck composed in any situation—hauling heavy loads, hitting the trails, or cruising on the highway. 

Push Harder with Optional Bump Stops

Choose between factory-style rubber bump stops or upgrade to FOX 2.0 Factory Race Series hydraulic bump stops. The rubber stops provide reliable protection for everyday use, while the FOX 2.0 hydraulic option absorbs hard hits, landings, and full-travel events for aggressive off-road performance.

Indexing Ring Options

This kit comes standard with a 6-bolt indexing ring kit. RAM 3500 trucks equipped with the optional Aisin heavy-duty 6-speed transmission use a different 8-bolt transfer case pattern. For these models, BDS offers an 8-bolt kit that includes an internal shaft seal extension and new shaft seal.
