Built for classic Chevy and GMC 3/4-ton owners who want a leveled stance without sacrificing ride quality, this 2-inch lift kit raises your front end to match the rear for a factory-like, more aggressive look. You'll gain improved ground clearance and the ability to fit up to 33-inch tires with proper wheel backspacing, all while preserving the balanced on-road and off-road performance Rough Country is known for.

Installed and serviced at Road Runner Wheels & Tires. Most leveling kits go in the same day. Call (678) 400-6467 to schedule.

What's included

  • Front lifted leaf springs (pair) — Raise the front end to match rear height while maintaining ride quality and performance.
  • 2-inch rear lift blocks — Keep the rear suspension geometry optimized after the front is lifted.
  • N3 shock absorbers (pair) — Premium 10-stage variable high-pressure nitrogen-charged shocks with 18mm spring-loaded piston rod and 54mm shock body for smooth highway comfort and off-road capability.
  • Brake line relocation brackets — Maintain proper brake-line angles and prevent stress on hoses after lifting.
  • U-bolts and hardware — All fasteners needed for secure installation.

Important notes

  • Vehicles equipped with a front sway bar should use drop brackets (SKU: 1019) — recommended to preserve suspension geometry and control.
  • Vehicles with factory quad shocks (dual shocks per side) will use a single aftermatic shock per side in this kit.
  • Maximum recommended tire size is 33 inches with proper wheel backspacing.

Why customers pick this at Road Runner

  • Rough Country Lifetime Replacement Warranty backed by a local, authorized dealer.
  • Professionally installed by techs who perform these kits every week — your truck gets the attention it deserves.
  • In-house alignment performed as part of every lift install to correct caster and maintain proper driveline geometry.
  • Premium N3 shocks tuned specifically for your vehicle — not a one-size-fits-all approach.
