4 Inch Lift Kit | At4/trailboss | Vertex | Chevy/gmc Sierra 1500 (19-24)/silverado 1500 (19-24)

Built for Chevy Silverado and GMC Sierra 1500 owners who want a commanding stance with genuine off-road geometry, this 4-inch Vertex lift kit raises and levels your truck while preserving factory ride quality. The cast-steel knuckle design and precision-cut components deliver durability that handles extreme terrain, and the high-clearance crossmember keeps suspension geometry dialed in — so you gain tire clearance (up to 35-inch rubber) without sacrificing handling.

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

• Front and rear knuckle boxes — cast-steel construction resists extreme stress and maintains precise geometry alignment.
• Crossmember kit — high-clearance design optimizes suspension travel and protects the undercarriage.
• Front skid plate — reinforces chassis strength during off-road use and protects vital components.
• Vertex 2.5 adjustable front shocks (pair) — tuned N3 series dampers deliver balanced on- and off-road performance without compromising factory ride feel.
• Vertex 2.5 rear shocks (pair, 7-inch) — matched rear valving supports the lifted geometry and handles payload.
• Universal hardware kit — brackets, fasteners, and installation components needed for a complete lift.
