{"product_id":"billet-aluminum-pulley-kit","title":"Billet Aluminum Pulley Kit","description":"The 2JRacing lightweight pulley combo set is engineered to enhance the performance of your Sentra Spec-V's QR25s engine. This comprehensive kit includes a billet 6061 aluminum crank pulley, a matching power steering pulley, and a new, longer belt to accommodate the pulley changes. The pulleys are designed to significantly reduce rotational mass; they weigh 80% less than the stock components (1lb vs. 5.1lbs), which directly translates to quicker revving and improved throttle response.\n\nInstallation is straightforward, described as a simple bolt-on modification that can typically be completed in under 30 minutes. The primary benefit cited is a net gain of 5 horsepower and 5 torque at the wheels. The billet 6061 construction ensures durability and a premium appearance, with options for red, blue, or black finishes for both pulleys.\n\nThis pulley set is specifically designed for the 2.5L Sentra B15sr models. It is crucial to note that this kit does not fit B16 models, as they utilize electric power steering systems.","brand":"2jracing","offers":[{"title":"Default Title","offer_id":52686677213496,"sku":"combopulley","price":159.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660670201.jpg?v=1784875842","url":"https:\/\/store.motormia.co\/products\/billet-aluminum-pulley-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
