6 Inch Lift Kit | M1 Struts/m1 | Chevy Silverado 1500 4wd (2025-2026)

Built for Chevy Silverado 1500 4WD owners who want commanding height without sacrificing ride quality — this 6-inch lift kit raises and levels your truck while preserving factory suspension geometry through precision-engineered steel knuckles, drop crossmembers, and optimized strut spacers. You'll gain clearance for 35" to 37" tires and retain that factory-like handling that makes daily driving predictable.

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 — structural frame components engineered for 2025 Silverado 1500 and Sierra 1500 fitment.
• 6-inch Driver and Passenger Knuckle Boxes — heavy-duty cast knuckles that reduce CV angles and maintain near-factory suspension geometry during lift.
• 6-inch Crossmember Box — drop-designed to preserve ideal suspension angles and accommodate the added height.
• Front Skid Plate — fabricated steel protection for undercarriage components.
• M1 Loaded Strut Pair — upper strut spacers with uncompromised strength and rigidity for confident lift without flex.
• M1 Monotube Shock Pair (Rear) — rear shocks paired with fabricated blocks and U-bolts to maintain factory-like geometry in back.

Important notes

• Requires cutting and drilling during installation.
• Does NOT fit LT Trail Boss, Custom Trail Boss, or ZR2 models — those trucks have factory 2-inch lifts and/or Multimatic DSSV dampers incompatible with this kit.
• Does NOT fit factory wheels — 20-inch or larger aftermarket wheels are required.
• Wheels must have 4.5-inch backspacing to fit properly. Some aftermarket wheels may require a 0.25" wheel spacer.
• Test fit wheels prior to final installation to confirm clearance.
