Built for diesel RAM 3500 owners who want aggressive 4-inch lift without compromising ride quality or steering geometry. This radius arm kit from BDS Suspension delivers 4 inches up front and 3 inches in the rear, with diesel-tuned Pro-Ride coil springs and steering correction engineered to keep your truck planted and responsive. Supports up to 37×12.5 tires.
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 — diesel-specific progressive-rate springs tuned for smooth, predictable ride across pavement and trail.
- Tubular Radius Arms — high-strength construction with caster adjustment built in; factory-style rubber bushings keep it quiet and service-free.
- Forged Drop Pitman Arm & Track Bar Bracket — steering geometry correction that re-centers the axle and minimizes steering angle as you lift.
- Bump Stops & Brake Line Brackets — safety and durability essentials that come complete.
Out back
High-strength fabricated lift block, longer u-bolts, and matched rear shocks complete the 3-inch lift and keep axle articulation smooth.
Pick your shocks
- BDS NX2 Nitro Series — smooth, controlled ride for daily driving and weekend hauling; nitrogen-charged for consistent performance across load ranges.
- FOX 2.0 Performance Series — premium damping for serious off-road duty; adjustable external reservoirs let you dial in terrain-specific comfort.
Important notes
- Maximum tire size is 37×12.5 — larger tires will contact body or suspension components.
- Kit is engineered for non-air-ride RAM 3500 models only (2013–2018 4WD diesel). Air suspension trucks require different geometry and are not compatible.
- Radius arm design preserves factory steering feel and driveline geometry; no additional modifications needed.
Why customers pick this at Road Runner
- BDS kits installed by technicians who run these every week — geometry-critical work done right the first time.
- Diesel-specific tuning means springs, shocks, and ride quality are matched to your engine's weight and power band.
- Caster correction and track bar geometry pre-engineered — no guesswork, no comebacks.
- Local BDS warranty support backed by Road Runner's reputation.
