{"product_id":"billet-serpentine-belt-tensioner","title":"Billet Serpentine Belt Tensioner","description":"The Katech KAT-A4425-BLK Billet Serpentine Belt Tensioner is engineered to eliminate belt slip and accessory drive failures, particularly during high-RPM or performance driving conditions. Developed from Katech's experience with the C5-R race program, this tensioner provides superior rigidity and consistent belt tension compared to stock units.\n\nConstructed from USA 6061-T6 billet aluminum and optimized using FEA, this tensioner ensures strength and precision. It utilizes an OEM-style pulley with raised belt keepers to prevent belt walk and maintain alignment. The high-load spring mechanism guarantees consistent tension even under extreme loads.\n\nInstallation is designed to be quick, often under 15 minutes. However, stanchions are sold separately (part number KAT-4428), and two are required for F-body and GTO applications. Specific belt part numbers are also noted: Gates K060827 for 2010-2012 Camaro and Gates K060790 for 2013-2015 Camaro.\n\nThis tensioner is compatible with LS1, LS2, LS3, LS6, and LS7 engines found in vehicles such as the Corvette, CTS-V, Camaro, Firebird, GTO, G8, and SS. It is important to note that this tensioner is not recommended for use on supercharged engines unless the supercharger has a dedicated drive system.","brand":"Katech","offers":[{"title":"Default Title","offer_id":52662801760568,"sku":"KAT-A4425-BLK","price":165.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687498735.jpg?v=1784321145","url":"https:\/\/store.motormia.co\/products\/billet-serpentine-belt-tensioner","provider":"MOTORMIA","version":"1.0","type":"link"}
