Aluminum Pulley Kit

By slowing down the accessory drive belt speed, this kit allows the engine to operate more efficiently, potentially leading to increased horsepower. Constructed from aerospace-grade 6061 aluminum, these pulleys offer both strength and lightweight characteristics. The kit includes the alternator, water pump, and crank pulleys, all finished in a natural aluminum appearance. The crank pulley is a one-piece design that incorporates a vibration dampener. This pulley kit is compatible with 4.6L engines. Specific applications mentioned include the 2011+ Ford Mustang 5.0L / 5.2L engine, and mid-01-04 GT Mustangs. The installation is generally considered straightforward, with a water pump pulley replacement estimated to take approximately 30 minutes for a beginner.
