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

Built for RAM 2500 owners who want maximum tire clearance without sacrificing ride quality or geometry. This 4-inch lift kit converts your factory rear air suspension to a coil-spring setup up front and adds a 4-Link conversion that corrects caster and axle positioning — so your truck handles better, climbs harder, and fits up to 35" tires while keeping factory sensor function intact.

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

• Pro-Ride Coil Springs — Gas-specific, progressive-rate springs engineered from high-tensile steel with the right wire diameter to deliver 4 inches of lift without premature bind.
• 4-Link Conversion — Bolt-on upgrade with 1/4-inch steel brackets and HD upper/lower control arms that optimize suspension geometry, limit caster change, and add strength and stability.
• Steering Correction — Forged drop pitman arm and heavy-duty track bar bracket keep steering in phase through suspension travel and recenter the axle.
• Bump Stops & Brackets — Brake line brackets and precision-tuned bump stops complete the front assembly.

Out back

Heavy-duty air bag spacers, track bar relocation bracket to correct axle positioning, bump stop extensions, and sway bar links keep your rear end dialed in. New air ride leveling sensor brackets reposition the ride height sensors so the air suspension performs just like factory height and maintains full bag range of motion.

Pick your shocks

• BDS NX2 Nitro Series — Comfortable, responsive daily-driver shocks tuned for smooth suspension travel on road and trail. Nitrogen charge eliminates fade and extends life.
• FOX 2.0 Performance Series — Premium two-stage damping for aggressive off-road use and high-speed stability. Tuned specifically for lifted trucks.

Important notes

• Fits 2014–2018 RAM 2500 gas models with rear air suspension only — not compatible with diesel.
• Maximum tire size: 35 x 12.5 inches.
• 4-Link conversion includes caster correction to preserve driveline geometry and steering feel.
• New air ride sensor brackets required to maintain factory leveling function at lifted height.
