{"product_id":"si-series-main-bearing-set-1","title":"SI-Series Main Bearing Set","description":"The King Racing MB4549SI is a set of SI-Series main bearings engineered for OE applications and aftermarket engine rebuilding.\n\nConstructed from a bi-metal material with a silicon aluminum composition (2.5-3% silicon), these bearings provide enhanced strength. They feature an improved crankshaft finish that helps mitigate issues with improperly ground or polished nodular cast iron crankshafts. The MB4549SI is designed for use with factory crankshafts and is suitable for performance engines as well as standard gasoline or diesel engine rebuilds.\n\nThis bearing set is compatible with a wide range of Ford, Lincoln, and Mazda vehicles equipped with the 3.5L EcoBoost V6 and 3.7L V6 engines, spanning model years from 2007 to 2019. Specific applications include various trims of the Ford Edge (2015-2018), Expedition (2015-2017), and other models, as well as certain Lincoln and Mazda vehicles. Always verify fitment for your specific vehicle's year, make, model, and engine. The bearings are sold as a set of 4 and are a direct replacement for stock applications, maintaining stock undersize specifications.","brand":"King Racing","offers":[{"title":"Default Title","offer_id":52686484373816,"sku":"MB4549SI","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/658279825.jpg?v=1784874297","url":"https:\/\/store.motormia.co\/products\/si-series-main-bearing-set-1","provider":"MOTORMIA","version":"1.0","type":"link"}
