{"product_id":"s-s-crankshaft-assembly-for-evolution-big-twin-engine","title":"S\u0026S Crankshaft Assembly for Evolution Big Twin – Engine","description":"\u003cp\u003eThese crankshaft assemblies for Evolution Big Twin are a direct replacement for 1984-1989 models and also work in 1990-1999 models when installed in conjuction with the pinion shaft gear parts as listed below. 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.\u003c\/p\u003e\n\u003cp\u003eS\u0026amp;S crankshaft for 1984-1999 Evolution Big Twin\u003c\/p\u003e\n\u003cp\u003eS\u0026amp;S Flywheel Assembly BT84-89 (BT84-99)\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Crankshaft Parts\u003c\/li\u003e\u003c\/ul\u003e","brand":"S\u0026S Cycle","offers":[{"title":"Default Title","offer_id":62567685620042,"sku":"752245","price":1872.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/standard-rgba_da82c6e5-edcb-4261-9e47-83c0af11c037.png?v=1782773736","url":"https:\/\/partsdenmark.com\/it\/products\/s-s-crankshaft-assembly-for-evolution-big-twin-engine","provider":"Parts Denmark","version":"1.0","type":"link"}
