6 Inch Lift Kit | Vertex/v2 | Gmc Sierra 1500 2wd/4wd (2025-2026)

Built for GMC Sierra 1500 owners who want commanding height without sacrificing suspension geometry — this 6-inch lift kit combines steel knuckles, drop crossmembers, and adjustable Vertex shocks to preserve factory suspension angles while gaining serious clearance. Run 35"–37" tires and keep your truck handling like it was engineered to.

What's included

• Universal Kit Box — core structural components for 2025 Sierra 1500 integration.
• 6-inch Driver & Passenger Knuckle Boxes — cast knuckles engineered to reduce CV angles and maintain suspension geometry while handling rugged terrain.
• 6-inch Crossmember Box — drop design that preserves ideal suspension angles across the full lift range.
• Front Skid Plate — heavy-duty protection for undercarriage components.
• Vertex 2.5 Adjustable 8-Step Front Struts (Pair) — tunable damping lets you dial in ride quality; upper spacers deliver uncompromised strength and rigidity.
• V2 Monotube Shock Pair — rear shocks paired with fabricated blocks and u-bolts to retain factory-like geometry in back.
