{"product_id":"5-3-vvt-camshaft-performance-package","title":"5.3 VVT Camshaft Performance Package","description":"The Texas Speed 5.3 VVT Camshaft Package provides a complete solution for upgrading GM truck engines featuring Variable Valve Timing. Since 2007.5+ engines use a computer-controlled cam phaser to optimize valve timing for efficiency, designing a performance cam is complex. Texas Speed leverages its Superflow 902 engine dyno to custom-engineer these camshafts and includes specific phaser tuning tables to ensure proper operation after installation.\n\nEach package contains the selected TSP VVT camshaft, valve springs, a set of 16 hardened pushrods, and a Comp Cams phaser limiter kit (#5456). The phaser limiter is mandatory to restrict cam timing movement from 50° to 20°, ensuring necessary piston-to-valve clearance for performance profiles while maintaining VVT functionality. An upgraded 8620 cam core is available upon request.\n\nPlease note specific GM cam phaser compatibility: these camshafts are designed for use with GM cam phaser #12606358, which is standard on all 2009+ trucks and some 2008 models. If you have a 2007 or early 2008 truck, you will require cam phaser #12606358, which must be verified by reading the part number directly off the factory phaser. Professional calibration is required to properly tune the camshaft phaser after installation.","brand":"Texas","offers":[{"title":"Default Title","offer_id":52663966040376,"sku":"TSP-25-TruckVVTCamPkg","price":699.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687144783.jpg?v=1784331326","url":"https:\/\/store.motormia.co\/products\/5-3-vvt-camshaft-performance-package","provider":"MOTORMIA","version":"1.0","type":"link"}
