Replace the original steel one-piece supercharger pulley on your LT4-powered vehicle with our precision-machined 3-piece unit. Our proven design for this application uses an electroless nickel-plated pulley hub CNC-machined from high grade steel, with a 2.30" aluminum drive ring and stock-appearing front pulley cover. The ring and cover are anodized in black, and all included fasteners are stainless steel or silver zinc plated.
This pulley installs as a direct replacement for the original 2.50” unit, and yields 1.5 - 2.5 lbs of boost. The original supercharger belt (or an equivalent) can be retained.
Tuning is required.
