Built for Chevy Silverado 1500 owners who want a commanding stance and serious off-road capability — this 6-inch suspension lift combines factory-geometry preservation with enough tire clearance to run 35" to 37" rubber. A full front and rear overhaul with steel knuckles, drop crossmember, and N3 struts keeps your truck planted while you climb.

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

What's included

  • Universal Kit Box (Mono Leaf Rear) — rear suspension foundation with mono-leaf architecture to maintain factory-like geometry and durability.
  • 6-inch Driver and Passenger Knuckle Boxes — heavy-duty cast knuckles engineered to reduce CV angles and preserve steering geometry.
  • 6-inch Crossmember Box — drop-design component that maintains suspension angles under lift height.
  • Front Full Skid Plate — underbody protection for articulation and trail work.
  • N3 Shock Pair — nitrogen-charged rear shocks tuned for the 6-inch height.
  • Loaded Strut Pair (6-inch) — front struts with integrated upper spacers for lift and ride control.

Important notes

  • Requires cutting and drilling during installation.
  • Does NOT fit LT Trail Boss, Custom Trail Boss, or ZR2 models — these are equipped with factory 2-inch lifts and/or Multimatic DSSV dampers incompatible with this kit.
  • Does NOT fit factory wheels. Aftermarket wheels (20-inch or larger) are required with a minimum of 4.5-inch backspacing. Some wheels may need a 0.25-inch spacer (#1065).
  • Test-fit wheels before finalizing your order to confirm clearance.

Why customers pick this at Road Runner

  • Factory geometry preserved — steel knuckles and drop crossmember keep suspension angles close to OEM specs, so your truck handles and rides like it was engineered this way.
  • Rough Country lifetime warranty backed locally — we stand behind every install and can handle warranty work on the spot.
  • Professional installation by techs who run these kits every week — experience means faster turnaround and zero comebacks.
  • Alignment performed in-house as part of every lift install — your truck leaves with a fresh four-wheel alignment, no guesswork.
  • 35" to 37" tire clearance in one package — no guessing about what fits; we'll confirm wheel and tire combos before you commit.
