{"product_id":"drive-belt-tensioner-assembly","title":"Drive Belt Tensioner Assembly","description":"The Pro-fiber 38172 drive belt tensioner assembly is designed to ensure proper belt tension, alignment, and damping for superior engine performance. Featuring a 6-groove flanged pulley with a 2.76-inch outside diameter, this unit utilizes a durable torsional spring design to minimize noise and vibration, promoting smoother operation and increased longevity of the drive system components.\n\nThis tensioner is compatible with 2002-2010 Chevrolet Silverado 2500 and 3500 models, as well as 2002-2010 GMC Sierra 2500 and 3500 trucks equipped with the 6.6L engine. Please note that compatibility varies significantly based on alternator amperage; specifically, it is for use on 2002 models with a 130A alternator and vacuum pump, 2003-2005 models with a 145A alternator and vacuum pump, and various 2006-2010 configurations requiring 125A or 145A alternators. It is not compatible with models that do not meet these specific alternator and equipment requirements.\n\nInstallation of this assembly is intended to be a direct-fit replacement for specified OE numbers, including 36310, 38172, and K061195HD. The unit is constructed with anti-deformation materials to maintain structural integrity under extreme operating conditions. Proper installation is recommended to ensure the consistent tension required for optimal alternator function and overall accessory drive health.","brand":"Pro-fiber","offers":[{"title":"Default Title","offer_id":52663366713656,"sku":"38172","price":66.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687529901.jpg?v=1784326287","url":"https:\/\/store.motormia.co\/products\/drive-belt-tensioner-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
