Focus mk3 ST 2.0 Ecoboost Lightweight Pulley Kit

The best way to free up existing power is to lighten up the rotating mass on the engine pulley kit. These lightweight pulleys shave off almost 4lbs compared to OEM, a weight savings of nearly 60%. The full kit includes a crank pulley, tensioner, water pump pulley and idler pulley; all of which are all precision CNC machined from high quality aircraft grade billet aluminum for years of durability and excellent appearance. The lightweight design greatly reduces mass and inertia, allowing for added hp & tq, increased throttle response, quicker revving and faster turbo spool-up.

Available in Natural Aluminum as well as Red, Blue & Black Anodized finish complimenting any engine bay.

Professional installation of crank pulley is recommended.
