{"product_id":"6-rib-5-bolt-3-5-inch-pulley","title":"6-Rib 5 Bolt 3.5-Inch Pulley","description":"The Whipple Superchargers 6-Rib 5 Bolt Pulley offers a 3.5-inch running diameter, designed to provide a boost in performance for compatible supercharger systems. Each pulley is meticulously machined from 6061-T6 billet aluminum, ensuring robustness and longevity. The hard-coated black anodized finish not only provides a sleek aesthetic but also offers superior wear and environmental protection.\n\nEngineered with advanced lightweight pockets, this pulley actively works to lower reciprocating mass, contributing to a more efficient and responsive system. Additionally, an integrated guard feature is incorporated to help manage and prevent unwanted belt wandering, even during demanding driving conditions. The running diameter is clearly engraved on each pulley for easy identification.\n\nA general rule of thumb suggests that every 0.125 inches of pulley change can result in approximately 1 psi of additional boost. It is important to note that Whipple Supercharger pulleys are application-specific, and this pulley is intended for particular Whipple supercharger configurations. Returns or exchanges are not accepted for used pulleys. Compatibility should be carefully verified before purchase.","brand":"Whipple Superchargers","offers":[{"title":"Default Title","offer_id":52866662105400,"sku":"SCP-63500-6","price":160.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687411411.webp?v=1787909448","url":"https:\/\/store.motormia.co\/products\/6-rib-5-bolt-3-5-inch-pulley","provider":"MOTORMIA","version":"1.0","type":"link"}
