{"product_id":"mcs-camshaft-roller-bearing-outer-rear","title":"MCS Camshaft roller bearing - Outer rear","description":"\u003cp\u003eOEM style 3-piece roller bearing that replaced the OEM 8990 ball bearing, used as the rear outer cam bearing from 2001-up. \nOEM replacement reference 8983. \n\nNote: H-D redesigned the Twin Cam rear outer cam bearing from ball (OEM 8990\/A) to a roller bearing style (OEM 8983\/MCS 921138) in 2001. This was done to help prevent failing ball bearings on, specifically, rear (=drive side) cams that are heavier loaded. This 01-up roller style bearing is a 3-piece design that is more heavy duty than a roller bearing. No other parts changed during the bearing changes. The early 99-00 style ball bearings will still fit all 99-06 models front \u0026amp; rear. Using front \u0026amp; rear ball bearings present no issues on cam driven gears.\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Cams bearings\u003c\/li\u003e\u003c\/ul\u003e","brand":"MCS","offers":[{"title":"Default Title","offer_id":63342034911562,"sku":"MSH-921138","price":226.0,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/921138k.jpg?v=1787727811","url":"https:\/\/partsdenmark.pl\/products\/mcs-camshaft-roller-bearing-outer-rear","provider":"Parts Denmark","version":"1.0","type":"link"}
