Built for Dodge W-Series owners who want a commanding stance and serious ground clearance, this 4-inch lift kit raises your truck above obstacles while preserving the stock ride quality that these classic leaf-spring rigs are known for. You'll gain up to 35 inches of tire clearance with proper wheel backspacing — all with a factory-like geometry thanks to the raised steering block and premium N3 shocks included.

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

  • 4-inch front leaf springs (pair) — lift the front axle while maintaining ride compliance and absorbing bumps without bottoming out.
  • 4-inch rear leaf springs (pair) — raise the rear to match front height and replace your factory-equipped block for a level stance.
  • Dana 44 steering block — corrects caster angle after the lift to preserve steering geometry and brake balance.
  • N3 shock pair (front) — 10-stage variable high-pressure nitrogen shocks with 18mm spring-loaded piston rod and 54mm body for rapid heat dissipation; tuned for both off-road compliance and highway smoothness.
  • N3 shock pair (rear) — matched rear shocks maintain ride quality and control articulation throughout the suspension travel.
  • Spring bushing & sleeve kit — isolates vibration and extends spring life by replacing worn factory bushings.
  • U-bolt kit — secures springs to axles with OEM-spec hardware.
  • Installation kit — all fasteners, brackets, and hardware needed to complete the install.

Important notes

  • Does NOT fit models with Cummins diesel engine.
  • ONLY fits models equipped with Dana 44 front axle.
  • Supports up to 35-inch tires with proper wheel backspacing — verify your wheel offset before purchasing.
  • New rear leaf springs replace your factory-equipped block; do not reuse OE rear springs.
