Built for Dodge W-Series owners who want classic truck presence with modern capability, this 4-inch lift kit raises your pickup's stance while preserving the factory ride geometry that made these trucks legendary. Rough Country pairs lifted leaf springs, a Dana 60 steering block, and premium N3 shocks to deliver ground clearance for 33–35 inch tires without sacrificing drivability on pavement or trail.

What's included

  • 4-inch front leaf springs (pair) — lifted and matched to your Dodge's geometry for increased ride height without compromising suspension travel or handling.
  • Dana 60 steering block — maintains correct caster and steering angles after the lift, keeping your truck's factory-like steering response intact.
  • 3-inch rear lift blocks (pair) — balance the front lift and preserve axle geometry for level stance and predictable handling.
  • N3 shock pair (front and rear) — Rough Country's 10-stage variable nitrogen-charged shocks with 54mm bodies and 18mm spring-loaded pistons blend off-road compliance with highway smoothness.
  • Spring bushings and sleeve kit — factory-pattern components that secure the new leaf springs and maintain geometry under load.
  • U-bolts and hardware — grade-stamped fasteners and installation kit with everything needed to complete the job.

Important notes

  • This kit is engineered for Dana 60 front axles only — confirm your truck's axle before ordering.
  • Does not fit Dodge W-Series models with Cummins diesel engines.
  • Maximum tire clearance is 35 inches with proper wheel backspacing — verify offset and width before purchasing wheels.
