4 Inch Lift Kit w/ Radius Arm | Ram 2500 (19-24) 4WD | Diesel

Built for diesel Ram 2500 owners who want 4 inches of lift, 35-inch tires, and a truck that drives like stock. This BDS radius arm kit lifts the front 4 inches and rear 2.5 inches while preserving steering geometry and driveline angles — no binding, no vibration, no surprises. Diesel-specific Pro-Ride coil springs, forged steering correction, and transfer case re-indexing keep your truck planted and predictable at any height.

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 diesel coil springs — full-length, progressive rate springs engineered for the extra weight of your diesel engine. High tensile steel with properly sized wire diameter eliminates premature coil bind.
• Heavy-duty tubular radius arms — replace soft factory stamped steel with forged strength. Factory-location mount with caster adjustment and OE-style rubber bushings for smooth, quiet operation.
• Forged drop pitman arm & track bar bracket — corrects steering geometry so your truck tracks true through full suspension travel, keeping front axle centered and steering angle minimized.
• Sway bar relocation and brake line brackets — clears suspension movement and protects brake lines.
• Transfer case indexing ring and new transmission crossmember — allows factory front driveshaft to function at 4 inches of lift without binding or angle issues.

Out back

Progressive rate Pro-Ride coil springs match the front for balanced ride quality. Track bar relocation bracket re-centers the rear axle, bump stop extensions prevent bottoming, and sway bar links maintain lateral control. Rear lifts 2.5 inches to complement the front and keep your truck level.

Pick your shocks

• BDS NX2 Nitro Series — comfortable, tuned daily driver performance at the lowest price point. Nitrogen charged for consistency across temperature and load.
• FOX 2.0 Performance Series — street-focused damping with more refinement over rough terrain than NX2, better for mixed driving.
• FOX 2.5 Performance Elite — premium adjustable compression and rebound tuning. Best for aggressive off-road use or fine-tuned comfort on the street.

Important notes

• Kit supports up to 35 x 12.5 inch tires maximum. Larger sizes will require trimming or other modifications.
• Transfer case re-indexing is required and included — this allows the factory front driveshaft to remain in service. Without it, driveshaft binding or failure can occur.
• New transmission crossmember supplied and must be installed for proper drivetrain clearance.
• Fits all 2019–2024 Ram 2500 4WD diesel models, including Tradesman, Lone Star, Big Horn, Rebel, Laramie, and Laramie Limited trims.
