6 Inch Lift Kit | Diesel | Chevy Silverado 1500 4wd (2019-2024)

Built for Chevy Silverado 1500 diesel owners who want commanding ground clearance without sacrificing geometry — this 6-inch lift kit combines steel knuckles, differential brackets, and drop crossmembers to preserve factory suspension angles while gaining serious height. You'll clear up to 37-inch tires and maintain balanced front-to-rear stance on and off-road.

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

• 6-inch front lift kit box — engineered steel components with upper strut spacers that preserve OEM-style track width and factory handling dynamics.
• Heavy-duty cast knuckles (driver and passenger) — reduce CV angles and simulate factory angles for smooth on-road handling and off-road capability.
• High-clearance crossmember — optimized to enhance suspension geometry without limiting ground clearance or tire fitment.
• Rear blocks, shocks, and U-bolts — retain factory-like rear geometry and allow you to run 35–37 inch tires without modification.
• Shock/strut options — choose from nitrogen-charged N3 shocks to premium Vertex reservoir shocks to match your ride-quality preference.
