KraftWerks Cogged Pulley - 70mm Cogged 42mm Width (6 Bolt / Must Use Adapter Hub)

This 70mm cogged pulley from KraftWerks is built with a 42mm width and features a 6-bolt mounting pattern, meaning it requires a separate adapter hub for installation. Cogged pulleys are known for their ability to grip the belt more securely, which helps prevent slippage, especially under high boost conditions. This improved grip is crucial for maintaining consistent supercharger speed and delivering reliable boost to your engine.

The design of this pulley is intended to work with supercharger systems that utilize Rotrex traction-drive technology, which can achieve very high shaft speeds. By using a cogged belt and pulley combination, you ensure that the supercharger spins at the speed dictated by the engine's RPM, leading to more predictable power delivery across the entire RPM range. This makes it a solid option for those looking to optimize their forced induction setup for street or track use.
