What does an under-drive pulley do?

An under-drive pulley slows down accessories like the alternator relative to engine speed. This reduces the parasitic drag on the engine, potentially freeing up a small amount of horsepower and improving throttle response.

What is this pulley made of?

This alternator pulley is constructed from aluminum, which offers a good balance of being strong and lightweight.

Will this pulley affect my car's electrical system?

Slowing the alternator can reduce the amount of electrical current it produces. While this pulley is designed to minimize negative impacts, it's always a good idea to monitor your car's electrical system performance after installation, especially if you have many high-draw accessories.

Product Details

This product is an under-drive alternator pulley for your Mitsubishi EVO 4 through 9. It's designed to reduce the load on your engine by slowing down the alternator's rotation speed compared to the stock pulley.

By slowing the alternator, this pulley helps free up a small amount of horsepower that would otherwise be used to spin the alternator. This can lead to a slightly improved throttle response. The pulley is made from well-built aluminum for a good balance of strength and light weight. It fits right onto your existing setup, making it a straightforward swap for enthusiasts looking to get a little more out of their engine.
