{"product_id":"serpentine-belt-tensioner-assembly-2","title":"Serpentine Belt Tensioner Assembly","description":"The Dayco 89377 automatic serpentine belt tensioner assembly provides a robust solution for vehicles equipped with 5.7L, 6.1L, and 6.4L HEMI engines. Its construction features a single, flat pulley measuring 70mm in diameter and 25.9mm in width, engineered to provide stable belt contact and minimize slippage. The automatic tensioning mechanism dynamically adjusts to belt stretch and wear, maintaining consistent pressure for optimal performance and longevity of the serpentine belt system.\n\nOperating in a counterclockwise direction, the Dayco 89377 is specifically designed to meet the requirements of the accessory drive systems in numerous Chrysler, Dodge, Jeep, and Ram vehicles. This tensioner is crucial for preventing common issues such as belt squeal, improper belt tracking, and the premature failure of engine accessories. By ensuring proper belt tension, it contributes to smoother operation and helps address problems related to tension loss and belt misalignment.\n\nIt is important to note that this tensioner *does not fit some Truck models and some 5.7L non-SRT SUV models*. Always verify fitment for your specific vehicle configuration. Installation should be performed following the vehicle's service manual, ensuring correct belt routing and observing the specified counterclockwise rotation. Proper alignment and belt condition should be checked before finalizing installation.","brand":"Dayco Racing","offers":[{"title":"Default Title","offer_id":52687609856312,"sku":"89377 (or MWR Custom Spec)","price":73.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662653531.jpg?v=1784885607","url":"https:\/\/store.motormia.co\/products\/serpentine-belt-tensioner-assembly-2","provider":"MOTORMIA","version":"1.0","type":"link"}
