Built for Chevy Silverado 1500 owners who want a commanding lifted stance without sacrificing suspension geometry, this 6-inch lift kit combines adjustable front struts, heavy-duty cast knuckles, and rear blocks to raise and level your truck while preserving factory-like suspension angles. It supports 35"–37" tires and retains stock track width for proper wheel alignment and stability.

What's included

  • Universal Kit Box (Mono Leaf Rear) — The backbone of your rear suspension, engineered to work with Silverado platforms.
  • 6" Driver & Passenger Knuckle Boxes — Cast knuckles that reduce CV angles and maintain suspension geometry under lift.
  • 6" Crossmember Box — High-clearance drop crossmember that preserves suspension geometry and supports the front end.
  • Front Full Skid — Protective underbody plating for the front suspension components.
  • Vertex 2.5 Adjustable Front Struts (Pair) — Nitrogen-charged upper strut spacers offering uncompromised strength and rigidity for the 6" lift.
  • V2 Monotube Shock Pair — Rear shocks engineered to complement the lift geometry and handle lifted driving dynamics.

Important notes

  • Requires cutting and drilling of frame and suspension components.
  • Does NOT fit LT Trail Boss or Custom Trail Boss models — they are equipped with a factory 2-inch lift that is incompatible with this kit.
  • Does NOT fit ZR2 models — equipped with a factory 2-inch lift and Multimatic DSSV dampers.
  • Does NOT fit factory wheels. 20-inch or larger aftermarket wheels are required.
  • Wheels must feature 4.5" backspacing to fit properly. Some aftermarket wheels may require a 0.25" wheel spacer (#1065). Please test fit wheels prior to installation.
