4 Inch Lift Kit | Ram 3500 (13-18) 4WD | Diesel

Built for Ram 3500 diesel owners who need serious clearance and geometry that stays true — this 4-inch lift kit from BDS preserves driveline angles while delivering the tire room and stance you want. With your choice of block height and shock tier, you get a kit tuned specifically for the weight and torque of a diesel 3500.

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

• BDS upper control arms — engineered to correct caster and maintain geometry as the suspension articulates.
• Front coil springs — rated for diesel weight and tuned for the lift height you choose.

Out back

Rear leaf spring blocks keep geometry in check and deliver consistent ride quality across your 4-inch lift.

Pick your shocks

• BDS NX2 Nitro Series — responsive, durable daily-driver shocks that handle highway and back-road work without breaking the bank.
• FOX 2.0 Performance Series — external reservoir, easily adjustable damping — built for trucks that see serious terrain and towing.

Important notes

• This kit is engineered for 2013–2018 Ram 3500 4WD without factory air suspension.
• Maximum tire clearance and driveshaft geometry depend on your block height choice (2, 3, or 4 inches) — confirm your tire size and wheel offset with us before ordering.
