The ECS Tuning alternator pulley?is precisionmachined, then hard anodized for good looks, corrosion resistance, and durability. Far lighter than stock cast or a stamped steel pulley, it has?a lower moment of inertia that won't sap horsepower as it spools up from low speeds. Reduced mass aside, it is extremely strong and durable.
Carefully engineered as a directfit bolt on, our alternator pulley diameter?allows you to keep your existing tensioner, and use an easytosource stock length serpentine belt.
