Part number: 6A1 733 A. Enhance your Subaru EJ engine's performance with the Cusco Aluminum Pulley Set. This set cuts down on rotational mass compared to factory pulleys. The crank pulley in this kit weighs just 1.74LBS (790 g), far lighter than the stock 5.07LBS (2.3kg) one. The alternator pulley weighs 0.16LBS (76g), while the stock one is 0.66LBS (300g). This reduction in weight eases the engine's load, boosting throttle response and acceleration. Made from high - grade aluminum, these pulleys are powder - coated in Cusco's signature blue. This not only guards against rust and corrosion but also adds a sleek look to your engine bay. Color: Blue. Warranty: Manufacturer. Material: Aluminum. Pulley Ratio: Stock.

Using your Cusco Aluminum Pulley Set is straightforward. First, make sure your vehicle's engine is cool and turned off. Carefully remove the old factory pulleys and replace them with the ones from this set. It's a good idea to use the right tools and follow your vehicle's service manual for the best results. When it comes to maintenance, keep an eye on the pulleys during regular engine checks. Look for any signs of wear or damage. Since they're powder - coated, they're pretty resistant to rust, but if you live in a harsh environment, give them a wipe down occasionally to keep them in top shape. If you notice any unusual noises or performance issues, it might be time to have the pulleys inspected. And remember, always follow the manufacturer's warranty guidelines to make sure you're covered.
