3 Inch Lift Kit | Ram 2500 w/ Rear Air Ride (14-18) 4WD | Diesel

Built for diesel truck owners who demand a level stance, serious tire clearance, and driveline geometry that actually works — this 3-inch lift kit from BDS Suspension transforms your 2014–2018 RAM 2500 air-ride diesel into a capable, confident rig. You get proper caster correction, air-bag re-indexing so your suspension performs like factory, and room for 35-inch tires without compromise.

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

What you get up front

• Diesel-specific Pro-Ride coil springs — full-length, progressive-rate springs engineered for weight and load, with high-tensile wire that avoids premature bind.
• HD tubular radius arms — replaces stamped steel, mounted in factory location with caster adjustment built in for smooth, quiet operation across lift heights.
• 1-3/8" adjustable track bar — solid steel construction recenter the front axle at multiple heights to preserve steering geometry and prevent bump steer.
• Sway bar links & brake line brackets — keeps suspension articulation smooth and brake lines out of harm's way.

Out back

BDS supplies heavy-duty air-bag spacer brackets, a track-bar relocation bracket to correct axle geometry, and bump-stop extensions to prevent binding at full droop. Most importantly: new air-ride leveling sensor brackets re-position your factory sensors so the air suspension performs at the new lift height and maintains full range of motion — no loss of self-leveling capability.

Pick your shocks

• NX2 Nitro Series — comfortable daily driver with tuned damping for smooth highway manners and predictable off-road behavior.
• FOX 2.0 Performance Series — premium remote-reservoir damping for maximum control, faster rebound, and the confidence to push harder on rough terrain.

Important notes

• This kit is engineered for air-ride equipped RAM 2500 diesel trucks only — factory air suspension is required.
• Maximum tire clearance is 35 x 12.5 inches; exceeding this size may cause rubbing or suspension interference.
• Front lift is 3 inches via coil spring; rear lift is 2 inches via spacer. Total system lift varies 2–3.5 inches depending on load and setup.
• BDS air-ride sensor relocation is included — do not reuse factory sensor brackets at the lifted height, or air-bag self-leveling will fail.

Why customers pick this at Road Runner

• Radius arms with caster correction built in — no hunting for geometry; BDS got it right for this truck.
• Air-ride sensors re-indexed and bracketed — your truck's self-leveling works as designed, not broken by the lift.
• Installed same day by techs who do these every week — no guessing, no comebacks.
• BDS warranty backed locally — we stand behind every kit we bolt on.
• 35-inch tire ready out of the box — proper fender clearance, no rub, no trimming.
