6 Inch Lift Kit w/ 4-Link | Ram 3500 (19-24) 4WD | Diesel

Built for Ram 3500 diesel owners who demand 37-inch tire clearance without sacrificing ride quality or geometry — this 6-inch lift kit pairs a factory-optimized 4-Link conversion with diesel-tuned Pro-Ride coil springs and transfer case re-indexing to keep your front driveshaft working straight. You get correct caster geometry, sway bar relocation, steering correction, and a choice of three shock tiers — from budget-friendly NX2 Nitro to premium FOX 2.5 Performance Elite.

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) — full-length progressive-rate springs engineered for 6 inches of lift and a smooth, predictable ride across any terrain.
• 4-Link Control Arm Conversion — high-strength 1/4-inch steel brackets and HD upper and lower control arms optimize suspension geometry, eliminate caster change through wheel travel, and add structural strength.
• Steering Correction Kit — forged drop pitman arm and heavy-duty track bar drop bracket keep steering geometry in phase and recenter the front axle.
• Transfer Case Indexing Ring & Transmission Crossmember — allows the factory front driveshaft to operate at the correct angle without modification.
• Sway Bar Relocation & Brake Line Brackets — integrated hardware preserves factory safety systems.

Out back

The rear uses a high-strength steel lift block paired with longer u-bolts and your choice of shock tier — NX2 Nitro, FOX 2.0 Performance Series, or FOX 2.5 Performance Elite. Available with or without factory rear overload leaf springs, and fits both 6-bolt and 8-bolt axles.

Pick your shocks

• BDS NX2 Nitro Series — comfort-tuned nitrogen-charged shocks for daily driving and weekend trips. Best value.
• FOX 2.0 Performance Series — nitrogen-charged with damping adjustability for a firmer, more controlled ride on rough terrain.
• FOX 2.5 Performance Elite — premium external-reservoir design with enhanced cooling and full damping control for serious off-road use and towing.

Important notes

• Maximum tire clearance: 37 x 12.5 inches.
• Transfer case re-indexing ring and new transmission crossmember are included — required to keep the factory front driveshaft in correct angle.
• Kit is available for trucks with or without factory rear overload leaf springs; confirm your configuration before ordering.
• Fits both 6-bolt and 8-bolt rear axles — select the correct variant for your truck.
• Diesel-specific engineering; not compatible with gasoline models.
