{"product_id":"billet-serpentine-belt-tensioner-1","title":"Billet Serpentine Belt Tensioner","description":"The Katech KAT-A4425 Billet Serpentine Belt Tensioner is a precision-engineered upgrade for LS1, LS2, LS3, LS6, and LS7 engines found in vehicles like the Corvette, CTS-V, Camaro, Firebird, GTO, G8, and SS.\n\nCrafted from USA 6061-T6 billet aluminum and optimized through FEA analysis, this tensioner offers superior rigidity and consistent belt tension. It features an OEM tensioner pulley with raised belt guides to keep the belt centered and prevent it from walking off the pulley, ensuring perfect alignment. The high-load spring mechanism maintains tension even at sustained use above 7,000 RPM.\n\nInstallation is designed to be quick, often under 15 minutes, and includes necessary hardware for most applications. However, F-body and GTO applications require the separately sold KAT-4428. The tensioner has an anodized finish with a laser-etched Katech logo for durability and a clean look. It is important to note that this tensioner is not for supercharged engine applications unless the supercharger has a dedicated drive.","brand":"Katech","offers":[{"title":"Default Title","offer_id":52662801989944,"sku":"KAT-A4425","price":165.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687498733.jpg?v=1784321146","url":"https:\/\/store.motormia.co\/products\/billet-serpentine-belt-tensioner-1","provider":"MOTORMIA","version":"1.0","type":"link"}
