It is constructed from durable 4340 material and features a hardening surface treatment for enhanced wear resistance and longevity under demanding conditions. This crankshaft boasts a 77.70mm stroke, a 48.0mm crank pin, and a 55.0mm main journal, all contributing to improved engine performance and reliability.\n\nThe design incorporates a full 8-counterweight configuration. These counterweights are strategically placed on the arms to optimize the balance ratio against the inertia generated by the piston's up-and-down motion and the crankpin's rotational forces. This advanced balancing significantly reduces engine vibration and minimizes shaft bending, which is crucial for preventing uneven bearing wear and ensuring smooth operation at high speeds.\n\nKey specifications include a stroke of 77.70mm, a crank pin diameter of 48.0mm, and a main journal diameter of 55.0mm. The crankshaft is made from robust 4340 forged steel and has undergone a hardening surface treatment. It has a total weight of 44.1 pounds.","brand":"Tomei","offers":[{"title":"Default Title","offer_id":52873017131320,"sku":"TA204C-NS05A","price":3870.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/forged-8-counterweight-crankshaft-77-70mm-stroke-for","provider":"MOTORMIA","version":"1.0","type":"link"}
