6 Inch Lift Kit | Mono Leaf Rear | Vertex/v2 | Gmc Sierra 1500 2wd/4wd (25-26)

Built for GMC Sierra 1500 owners who want a commanding lifted stance with suspension geometry locked in factory-tight, this 6-inch lift kit raises your rig front-to-rear while maintaining ideal caster and suspension angles for superior handling. The kit supports 35″–37″ tires without additional modifications, and its mono-leaf rear design with V2 monotube shocks delivers the durability and control you need on aggressive terrain.

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 — The structural backbone of your rear suspension setup, engineered to integrate seamlessly with your Sierra's frame.
• 6" Kit Driver & Passenger Knuckle Boxes — Heavy-duty cast knuckles that reduce CV angles and preserve factory geometry for balanced ride quality.
• 6" Kit Crossmember — High-clearance design that maintains ideal suspension angles and supports the new lift height without compromising handling.
• Front Skid Plate — Fabricated steel protection for undercarriage components during off-road use.
• Vertex 2.5" Adjustable Front Strut Assemblies (Pair) — 8-step adjustability allows fine-tuning of ride height and damping to match your terrain and driving style.
• V2 Monotube Shock Pair (Rear) — Nitrogen-charged monotube shocks that handle extreme terrain with responsive dampening and zero fade.

Important notes

• Does NOT fit Denali or Denali Ultimate models equipped with Adaptive Ride Control.
• Does NOT fit AT4 or AT4X models — both come standard with a 2-inch factory lift; the AT4X also has Multimatic DSSV dampers incompatible with this kit.
• Does NOT fit factory wheels. Requires 20-inch or larger aftermarket wheels with 4.5" backspacing. Some wheels may require a 0.25" spacer — test fit before final installation.
• Installation requires minor cutting and drilling; a strut compressor is necessary. Professional installation is strongly recommended.
