KraftWerks Supercharger Ribbed Pulley - 105MM 7 Rib

This is a KraftWerks 105mm supercharger pulley, designed for serpentine belt systems. It features a 7-rib design, which helps ensure the belt stays firmly in place during operation, preventing slippage and maintaining consistent boost levels. This pulley requires an adapter hub for installation, which is sold separately.

The 105mm diameter is a specific size that affects the rotational speed of your supercharger relative to your engine's speed. A larger pulley on the supercharger will spin it slower, potentially reducing boost pressure but also lowering operating temperatures. Conversely, a smaller pulley spins the supercharger faster, increasing boost and power output, but also generating more heat. Choosing the right pulley size is key to tuning your forced induction system for your specific performance goals.

Please note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and any required adapter hubs.
