{"product_id":"mcs-camshaft-roller-bearing-outer-rear-mcs-921138","title":"MCS Camshaft Roller Bearing. Outer, Rear","description":"99-06 Twin Cam (Excl. 2006 Dyna) (NU) \u003cbr\u003e\u003cbr\u003eOEM style 3-piece roller bearing that replaced the OEM 8990 ball bearing, used as the rear outer cam bearing from 2001-up. Note: The MoCo 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.","brand":"Mcs Storehouse","offers":[{"title":"Default Title","offer_id":43567852322879,"sku":"mcs_921138","price":39.6,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0667\/3213\/0367\/files\/mcs_921138_b.jpg?v=1784732255","url":"https:\/\/vaultmoto.com\/products\/mcs-camshaft-roller-bearing-outer-rear-mcs-921138","provider":"VaultMoto","version":"1.0","type":"link"}
