{"product_id":"pulley-and-hub-kit","title":"Pulley and Hub Kit","description":"The core of this package is the pulley, which utilizes SPE's patent-pending CNC Convex Knurling Process (CKP). This unique machining process provides an ideal balance between belt grip and wear. The rib surface offers variable grip depending on belt load, with less aggressive contact under low boost for reduced wear and more aggressive wedging under higher boost demands. This ensures optimal grip without degrading the belt or the pulley surface over time, leading to more consistent performance and improved track times or dyno numbers.\n\nThe package also includes a lightweight, high-strength hub, available in either stainless steel or titanium. The titanium option is noted as the lightest supercharger hub on the market. SPE offers hardware in both titanium and stainless steel. The stainless steel bolts are polished, while the titanium bolts come in multiple anodized color options: black, blue, bronze, and green.\n\nThis pulley and hub package is compatible with CTSV, ZL1, and Z06 vehicles.","brand":"SPE Motorsport","offers":[{"title":"Default Title","offer_id":52866386067768,"sku":"SPE-L100109","price":210.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687688724.webp?v=1787906974","url":"https:\/\/store.motormia.co\/products\/pulley-and-hub-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
