The ECS Tuning three-piece underdrive pulley set is made of lightweight aluminum, and sized to create an overall underdrive pulley ratio for improved engine response and reduced parasitic losses from accessory loads.
These solid aluminum pulleys are precision-machined, then hard anodized for good looks, corrosion resistance, and durability. Far lighter than stock cast or stamped steel pulleys, they have a lower moment of inertia that won't sap horsepower as they spool up from low speeds. Reduced mass aside, they are extremely strong and durable.
The smaller diameter crank pulley, combined with a larger diameter power steering pulley and stock diameter alternator pulley, provide a combined underdrive pulley ratio that reduces parasitic accessory loads, leaving more power for acceleration.
Carefully engineered as a direct-fit bolt on, the balanced choice of pulley diameters allows you to keep your existing tensioner, and use an easy-to-source stock length serpentine belt.
Pulley Weights:
Alternator pulley - 108 grams
Power Steering pulley - 236 grams
Crank Pulley - 236 grams
To help install the alternator pulley easier, check out the alternator pulley install/removal kit es419.
