{"product_id":"camshaft-roller-bearing-outer-rear","title":"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. OEM replacement reference 8983. Note: 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","brand":"Mcs","offers":[{"title":"Default Title","offer_id":50010597687624,"sku":"921138","price":48.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2711\/4344\/files\/921138.jpg?v=1778998120","url":"https:\/\/holydeath.com\/products\/camshaft-roller-bearing-outer-rear","provider":"Holy Death Motorcycle Co.","version":"1.0","type":"link"}
