What's included

  • Box Kit — Complete lift assembly with all fasteners and hardware for your vehicle platform.
  • N3 Shock Kit — Nitrogen-charged shocks tuned to preserve factory ride quality while supporting the increased lift height.
  • Driver & Passenger Knuckles — Front-end geometry correction pieces that maintain proper caster and suspension angles after the lift.

Important notes

  • Fits 6-lug wheels only. Does not fit 2004–2006 models equipped with factory torsion bar front suspension.

  • Rear anti-wrap blocks are designed to prevent axle wrap and maintain stock ride characteristics at the new lift height.
