      Description

      Boosted Belt Efficiency. The Underdrive Alternator Pulley is engineered to reduce parasitic drag and increase usable horsepower in your 2010-2014 Ford Mustang GT500. Featuring a 25% underdrive, this pulley slows alternator rotation to reduce strain on the engine at high RPMs—ideal for performance applications. It's a smart upgrade for enthusiasts looking to free up engine power without compromising charging performance at idle.

      Construction and Appearance. Crafted from durable materials and finished in raw metal, this pulley is built for high-revving conditions. Capable of spinning between 17,000 and 18,000 RPM, it maintains structural integrity under extreme conditions while delivering a clean, race-inspired appearance under the hood.

      Installation. This component is a direct replacement, but it requires a longer belt to accommodate the altered pulley diameter. The installation process is adaptable with basic mechanical tools and can be completed in a home garage or professional shop, offering noticeable gains in efficiency with minimal modification.

      Application. This Underdrive Alternator Pulley fits 2010-2014 Ford Mustang GT500 Models. It reduces rotational drag for improved performance and throttle response, making it an excellent upgrade for high-performance builds and track-day setups.
