What's included

  • 4-inch front leaf springs (pair) — Lifted springs that raise the front end while preserving ride quality and factory-like geometry.
  • 4-inch rear leaf springs (pair) — Matched rear springs that maintain front-to-back balance and replace your factory block.
  • Dana 60 steering block — Raised steering geometry block that keeps caster and kickback angles correct after the lift.
  • N3 shock pair (front) — Premium 10-stage variable nitrogen-charged shocks with 18mm spring-loaded piston rods and 54mm bodies for smooth highway and off-road performance.
  • N3 shock pair (rear) — Matching rear shocks tuned to complement the lifted leaf-spring setup.
  • Spring bushings and sleeves kit — Replacement bushings and sleeves for secure spring attachment and durability.
  • U-bolt kits and hardware — All fasteners and mounting hardware needed to secure springs and components.
  • Installation kit — Complete hardware pack for assembly.

Important notes

  • Does NOT fit models equipped with the Cummins diesel engine.
  • ONLY fits models with Dana 60 front axle — verify your truck's axle type before purchase.
  • New rear leaf springs replace your factory-equipped block; the block is not retained.
  • This kit is engineered to fit up to 35-inch tires with proper wheel backspacing — confirm your wheel offset and tire size with our team before installation.
