Contrary to the OEM crankshaft in 1990-1999 models these crankshafts feature a separate sprocket shaft and pinion shaft, which makes a rebuild possible. Another great advantage is that the 1984-1989 style pinion shafts have proven to be much stronger as the OEM design used in 1990-1999 models. Crankshafts are ready to install and balanced by S\u0026amp;S for use with stock pistons. Great for engine new builds and rebuilds.\u003cbr\u003e Replaces OEM: 23906-93B","brand":"S\u0026S Cycle","offers":[{"title":"Default Title","offer_id":39523098755157,"sku":"Z752245","price":1779.87,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1606\/2595\/products\/standard-rgba_189c640d-667b-421a-9e2e-a972b8023958.png?v=1630688160","url":"https:\/\/california-motorcycles.com\/en\/products\/s-s-crankshaft-assembly-for-evolution-big-twin-for-harley-davidson-752245","provider":"California Motorcycles","version":"1.0","type":"link"}
