Kartboy Aluminum Crank Pulley EJ for Alternator Belt w/AC Pump Delete

This is the Kartboy aluminum crank pulley specifically made for EJ engines where the air conditioning pump has been removed. It's designed to work with the alternator belt, helping to clean up the engine bay and reduce the overall weight of rotating components. By swapping out the heavier stock pulley for this lighter aluminum version, you can expect a more responsive engine feel, especially when revving.

Kartboy is known for making well-built parts for Subaru enthusiasts, and this crank pulley is no exception. It's machined from aluminum, which makes it significantly lighter than the factory steel pulley. This weight reduction means less inertia for the engine to overcome, which can translate into quicker acceleration and a more eager throttle response. It's a popular modification for those looking to shed a bit of weight and improve the performance characteristics of their EJ-powered vehicle.
