4 Inch Lift Kit w/ Radius Arm | Ram 3500 w/ Rear Air Ride (19-24) 4WD | Gas

Built for Ram 3500 owners who want 4 inches of lift without sacrificing ride quality or driveline geometry. This kit adds serious ground clearance — up to 35" tires — while preserving the factory front driveshaft and transfer case function through a precision indexing ring and new crossmember. You get tubular radius arms with caster correction, progressive-rate Pro-Ride coil springs, and a forged drop pitman arm to keep your steering square under load.

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 — Full-length, gas-specific, progressive-rate springs engineered for your truck's weight and the 4-inch lift height. Smooth and predictable over any terrain.
• HD Tubular Radius Arms — Heavy-duty replacements for the factory stamped steel. They mount in factory locations, include caster adjustment for geometry correction, and ride on OE-style rubber bushings so you get a quiet, service-free install.
• Forged Drop Pitman Arm & Track Bar Bracket — Minimize steering angle and keep your front axle centered during suspension travel. Critical for square handling at this lift height.
• Sway Bar Relocation Hardware — Repositioned to work with your new ride height.
• Brake Line Brackets — Safety brackets keep hydraulic lines clear of suspension movement.
• Transfer Case Indexing Ring & New Crossmember — Allows the factory front driveshaft to stay in service without binding or angle stress. This is not a shortcut — it's engineered preservation of driveline integrity.

Out back

The rear uses a high-strength fabricated lift block, heavy-duty air bag spacers, and longer u-bolts to safely manage the extra height on your air-ride setup. Paired shocks complete the package and keep the back end planted.

Pick your shocks

• NX2 Nitro Series — Smooth, composed daily-driver shock. Full-time damping, built to last, and the value pick for most owners.
• FOX 2.0 Performance Series — Premium monotube design with speed-sensitive damping and a wider tuning window. Best for towing heavy or rough-road aggression.

Important notes

• This kit is engineered for gas-powered Ram 3500 models with factory rear air ride suspension only — not compatible with diesel or coil-spring rear setups.
• Maximum tire clearance is 35 inches. Verify backspacing and offset with your wheel choice to avoid brake-caliper or fender contact.
• The transfer case indexing ring is required to preserve the factory front driveshaft. This is not optional.
• Fits model years 2019–2024 Ram 3500 4WD only.
