Built for Dodge W-Series owners who want an aggressive stance with real capability, this 4" lift kit raises your pickup's ground clearance to clear obstacles while delivering that classic lifted truck look. The kit combines front leaf springs, a raised steering block, and premium N3 shocks to maintain a factory-like ride geometry even after lifting — and accommodates up to 35" tires with proper wheel backspacing.

What's included

  • 4" front leaf springs (pair) — Lifted springs deliver the core ride-height gain without sacrificing ride quality or performance.
  • Raised steering block — Maintains caster and geometry angles for a factory-like feel after lifting.
  • 3" rear lift blocks (pair) — Raises the rear axle in proportion to the front, keeping the chassis level.
  • N3 shock pair (front and rear) — Premium 10-stage variable high-pressure nitrogen-charged shocks with 18mm spring-loaded piston rods and 54mm bodies — tuned for both off-road articulation and smooth highway ride.
  • Spring bushings and sleeves kit — Replacements for worn or damaged suspension mounts.
  • U-bolts and hardware — Everything needed to secure the springs and blocks to your axles and frame.
  • Installation kit — Fasteners and brackets specific to your W-Series pickup.

Important notes

  • Kit is designed only for models with Dana 44 front axle. Does not fit Cummins diesel engines.
  • Maximum tire size is 35" with proper wheel backspacing. Confirm your wheel offset before installation to avoid rubbing or suspension contact.
