Nitto 4340 billet crankshafts are produced from a high quality, double melted true billet round bar stock – unlike many of our competitors who use forged materials or lower quality 4340 bar stock equating to lower cost. The higher quality materials, combined with our design features, prevents flex and promotes stability under load, enabling our cranks to rev smoothly. This is so you benefit from drastically reduced harmonics when compared to OEM and other aftermarket crankshafts.
During quenching, heat treatment and nitriding, our crankshafts are accompanied by a sample piece of material throughout each of these processes. This sample piece is sliced and metallurgically analysed in order to guarantee that the quenching, heat treatment and nitriding meet our high standards.
Our crankshafts may hold world records, but we strive every day to find the most marginal improvements to help you achieve your goals whether you’re on the street or track.
