{"product_id":"lightweight-pulley-kit-2","title":"Lightweight Pulley Kit","description":"The Agency Power AP-Z34-130 Lightweight Pulley Kit is engineered for performance enthusiasts seeking to optimize their Nissan 370Z, GT-R R35, or Infiniti G37 engines. This kit replaces essential stock pulleys with lighter, performance-oriented components, aiming to improve engine response and power delivery.\n\nThe kit consists of a 2-piece design featuring an underdrive and lightweight crank pulley, coupled with an overdrive alternator pulley. The underdriven nature of the crank pulley facilitates faster engine revving, while the significant weight savings from reduced rotational mass contribute to an increase in horsepower. This translates to a more responsive feel and enhanced overall engine performance.\n\nThey are precisely machined using advanced lathes and mills to ensure exact tolerances and a durable, long-lasting design. To address potential wear on the crankshaft, the crank pulleys incorporate a steel sleeve. Additionally, each crank pulley is equipped with a keyway for a secure and accurate fit and features strategically machined pockets to further reduce weight.\n\nThe combination of lightweight materials, precise engineering, and a focus on performance gains makes this pulley kit a valuable upgrade for compatible vehicles.","brand":"Agency Power","offers":[{"title":"Default Title","offer_id":52686851834168,"sku":"AP-Z34-130-HBFV","price":237.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660673414.jpg?v=1784877505","url":"https:\/\/store.motormia.co\/products\/lightweight-pulley-kit-2","provider":"MOTORMIA","version":"1.0","type":"link"}
