These pulleys are precision CNC machined from 6061 aluminum and finished with a military-spec hard anodization for exceptional durability.\n\nDesigned as a direct bolt-in replacement for the M156 and M159 engine families, this kit includes one 62mm grooved idler, one 76mm idler, one 54mm idler, and one 65mm idler. This makes them an ideal solution for both stock and highly modified applications.\n\nThe fitment includes various Mercedes-Benz models equipped with the M156 engine, such as the 2007-2011 SL63 AMG (Roadster R230), 2007 R63 AMG (Base W251), and 2011 ML63 AMG (Base W164).","brand":"Weistec","offers":[{"title":"Default Title","offer_id":52866628682040,"sku":"810089562265","price":584.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687410442.jpg?v=1787909391","url":"https:\/\/store.motormia.co\/products\/billet-idler-pulley-set-for-m156-m159-engines","provider":"MOTORMIA","version":"1.0","type":"link"}
