8 Inch Lift Kit w/ 4-Link | Ram 3500 (13-18) 4WD | Diesel

Built for Ram 3500 diesel owners who want 8 inches of lift without sacrificing ride quality or geometry. This BDS 4-link suspension kit delivers serious height, maintains proper caster angles, and keeps your driveline geometry dialed — all while supporting the weight of a diesel engine and payload. You get a choice of leaf spring or block-and-add-a-leaf configurations with either 6-bolt or 8-bolt rear axles, paired with your choice of shock tier.

Installed and serviced at Road Runner Wheels & Tires. Most kits go in the same day. Call (678) 400-6467 to schedule.

What you get up front

• 4-link suspension geometry — maintains factory caster correction and driveline angles so your truck rides stable at highway speeds and doesn't fight the steering.

Out back

Choose your rear configuration: full leaf springs (your choice of 6-bolt or 8-bolt axle housing) or a 5-inch block kit paired with an add-a-leaf for progressive support. Both handle the weight of a diesel engine and keep you level when towing or hauling.

Pick your shocks

• BDS NX2 Nitro Series — comfort-tuned for daily driving, smooth transitions, and a predictable ride on and off pavement.
• FOX 2.0 Performance Series — adjustable damping and speed-sensitive valving for aggressive terrain, rock crawling, and high-speed off-road work.

Important notes

• Diesel Ram 3500 models only (2013–2018 4WD). Air-suspension trucks are not compatible with this kit.
• Driveshaft loop or re-indexing may be required depending on your vehicle's current driveline setup — our technicians will assess during install.
• Tire clearance expands significantly with 8 inches of lift. Confirm your wheel offset and backspacing before ordering if you plan larger rubber.
