6 Inch Lift Kit | Mono Leaf Rear | Vertex | Chevy Silverado 1500 4wd (25-26)

Built for Chevy Silverado 1500 4WD owners who want commanding height without sacrificing suspension geometry, this 6-inch Vertex lift kit delivers a commanding stance while preserving factory-like suspension angles. You'll gain clearance for 35"–37" tires and maintain ride quality through precision-engineered steel knuckles, differential brackets, and drop crossmembers that keep CV angles as close to factory spec as possible.

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) — Foundation hardware for the rear suspension assembly.
• 6" Kit Driver & Passenger Knuckle Boxes — Heavy-duty cast knuckles engineered to reduce CV angles and maintain factory geometry while supporting the full 6-inch lift.
• 6" Kit Crossmember Box — Drop crossmember design that lowers the differential to simulate factory suspension angles and preserve ride quality.
• Front Full Skid Plate — Protects undercarriage components during off-road use.
• Vertex 2.5" Adjustable Front Strut Spacers (Left & Right) — Upper strut spacers offering uncompromised strength and rigidity to achieve lift height without compromise.
