Product Details

If you're looking to make your 1994-1998 Subaru Impreza feel more responsive, this 3-piece lightweight pulley kit from Go Fast Bits is a solid option. It replaces the stock crank, alternator, and power steering pulleys with lighter aluminum versions, and includes the necessary belts. By significantly reducing the rotating mass in your engine, you'll notice a quicker throttle response and a more eager feel when the engine revs up.

These pulleys are machined from a single billet of 6061-T6 aluminum, which is a strong and lightweight material. This construction helps reduce the inertia by up to 85% compared to the factory parts. This means less of your engine's torque is used just to spin the pulleys, and more can be sent to the wheels for improved acceleration. The kit is designed as a bolt-on performance upgrade, and GFB has tested these to ensure that even with the underdrive design, the performance of your accessories like the alternator and power steering won't be compromised.

This kit is a direct replacement for your stock pulleys and includes the belts you'll need for installation. It's a great way to get a more lively feel from your engine without needing other supporting modifications or tuning.
