6 Inch Lift Kit | Diesel | Chevy Silverado 1500 4wd (2025-2026)

Built for diesel Silverado 1500 owners who want commanding presence and capability without sacrificing suspension geometry, this 6-inch lift kit raises and levels your truck while preserving factory-like suspension angles through precision-engineered steel knuckles, differential brackets, and drop crossmembers. You'll gain clearance for 35"–37" tires and maintain the responsive handling that matters on and off the pavement.
