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

Built for Ram 3500 owners who want maximum capability without sacrificing ride quality — this 5.5-inch radius arm lift kit transforms your gas-powered truck with factory rear air suspension into a capable hauler that clears up to 37" tires while preserving driveline geometry through transfer case re-indexing and caster-corrected radius arms.

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 tuned to deliver consistent lift height across varied terrain.
• Tubular Radius Arms — heavy-duty replacement arms with integrated caster adjustment and OE-style rubber bushings for smooth, quiet operation — no creep, no maintenance headaches.
• Forged Drop Pitman Arm & Track Bar Bracket — maintains steering geometry and keeps the front axle centered through suspension travel.
• Sway Bar Relocation Kit — preserves anti-roll control at the new lift height.
• Transfer Case Indexing Ring & New Transmission Crossmember — allows the factory driveshaft to work safely with the lift without binding.
• Brake Line Brackets — prevents line chafe and maintains proper brake function.

Out back

The rear uses a high-strength steel lift block paired with a heavy-duty air bag spacer to maintain factory air suspension geometry. Longer u-bolts secure everything, and the kit includes a matching set of shocks to complement your front end.

Pick your shocks

• BDS NX2 Nitro Series — comfortable daily driver with nitrogen-charged damping, stable handling on and off pavement, and proven durability at this lift height.
• FOX 2.0 Performance Series — premium adjustability and responsive tuning for serious off-road work, rough terrain recovery, and maximum control.

Important notes

• This kit is engineered for gas-powered Ram 3500 models only (2019–2024) equipped with factory rear air suspension. Diesel models and those without air bags require different kits.
• Maximum tire clearance is 37 inches. Larger tires may contact body components or suspension parts.
• Transfer case re-indexing is required and included. The indexing ring and new crossmember must be installed to preserve driveshaft function and prevent binding.
• Factory OE wheels are recommended to avoid offset/backspacing conflicts with the new suspension geometry. Aftermarket wheels must be vetted for clearance — bring your specs when you call.
• ABS sensors and brake lines need attention during installation to prevent chafe or sensor malfunction. Our techs handle this as part of the install.
• Bumpstops are not modified; however, coil spring preload is tuned to prevent bottoming at the new ride height.

Why customers pick this at Road Runner

• Factory geometry correction baked in — our techs set caster, pitman arm drop, and track bar angle to spec every single time.
• BDS warranty backed locally — if something goes wrong, you're not shipping parts across the country; we handle it here.
• Installed by suspension specialists who bolt these kits together every week — not a one-off job at a quick-lube.
• Transfer case re-indexing done right the first time — no driveshaft vibration, no comebacks.
• Same-day service on most installs, so you're back on the road fast.
