Built for Dodge W-Series owners who want more ground clearance and aggressive stance without sacrificing ride quality, this 4-inch lift kit combines front and rear lifted leaf springs with premium N3 shocks to raise your truck while keeping factory-like handling and comfort. You'll gain clearance for up to 35-inch tires and a commanding presence that turns heads.

Installed and serviced at Road Runner Wheels & Tires. Most lift kits go in the same day. Call (678) 400-6467 to schedule.

What's included

  • Front lifted leaf springs (pair) — raise ride height at the front axle while maintaining leaf-spring geometry and factory compliance.
  • Rear lifted leaf springs (pair) — match front height and replace factory block springs to keep suspension geometry balanced.
  • N3 shock absorbers (pair, front and rear) — 10-stage variable high-pressure nitrogen-charged shocks with 18mm spring-loaded piston rod and 54mm shock body for smooth highway ride and off-road control.
  • Dana 44 steering block — raised geometry correction component that keeps steering angles optimum after the lift.
  • Spring bushings and sleeve kit — isolates leaf springs and maintains suspension pivot geometry.
  • U-bolt kit and hardware — secures springs to axles with proper clamping force and corrosion resistance.
  • Installation hardware kit — all fasteners and brackets needed for a complete bolt-together install.

Important notes

  • Does NOT fit models equipped with Cummins diesel engine.
  • ONLY fits models with Dana 44 front axle.
  • Rear leaf springs replace your factory-equipped block springs — factory blocks are not reused.
  • Proper wheel backspacing is required to safely fit 35-inch tires; consult with our team on fitment.
