{"product_id":"interchangeable-crank-pulley-kit-3","title":"Interchangeable Crank Pulley Kit","description":"The Metco Motorsports Interchangeable Crank Pulley Kit is a performance-focused upgrade designed for the 6.2L LSA engine found in 2009-2015 Cadillac CTS-V and 2012-2015 Camaro ZL1 models. Built around an SFI-approved Innovators West Super Duty balancer (PN 840\/1000SD), this kit provides a lightweight alternative to the factory steel unit, reducing rotating mass from 16.2 lbs to 12.6 lbs while offering advanced wet clutch harmonics-dampening technology.\n\nInstallation of the balancer is a direct-fit replacement for the factory unit. The kit features CNC-machined billet aluminum crank pulley rings that secure to the balancer with six socket-head fasteners, allowing owners to easily swap rings to adjust boost levels. A Super Duty Hub Upgrade is included, which is highly recommended for vehicles producing 750HP or more; this heavy-duty steel hub requires a new front cover seal, which is provided in the kit.\n\nCompatibility and configuration requirements must be noted: while 8.60\" and 9.10\" rings fit with the original 70mm crank idler pulley, the 9.55\", 10.00\", and 10.50\" pulley rings require the use of the Metco PN MRB1000 idler pulley relocation bracket to provide necessary clearance. Users should consult the Metco resources for supercharger belt length adjustments. A professional tune is recommended to safely manage increased boost levels.","brand":"Metco Motorsports","offers":[{"title":"Default Title","offer_id":52689067180344,"sku":"LSA","price":759.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687379775.jpg?v=1784901256","url":"https:\/\/store.motormia.co\/products\/interchangeable-crank-pulley-kit-3","provider":"MOTORMIA","version":"1.0","type":"link"}
