Nitto 4340 Billet Steel crankshafts are manufactured from high quality true billet round bar stock. Most other aftermarket crankshafts are manufactured using cast forged material, which is a much cheaper manufacturing process and hence carry a cheaper price tag, but their performance, strength and horsepower capabilities are significantly compromised compared to that of a true billet crankshaft. An engine with a 4340 billet steel crankshaft will rev faster and cleaner due to the different harmonics produced from the high grade material. Furthermore, we also offer our EN40B crankshafts in order to cater for the sector of the market that seek to produce power in excess of 2000hp reliably. The EN40B is stronger than 4340 and has stood the test of vigorous drag racing applications, with our EN40B Wide Journal RB32 crankshaft producing in excess on 25000hp at the engine in numerous builds and even achieving upwards of 3000hp in Promod applications. The EN40B material is superior to the 4340, offering the benefits of increased performance capabilities while weighing the same as 4340. All of our 4340 and EN40B cranks are 4340/EN40B Billet Round Bar Stock Grade Tested (X-ray - Sonic) Quenched and Heat Treated Fully Counter Weighted Nitrided Balanced Knife Edged (where applicable) 100% CNC Profiled 100% CNC Drilled and Tapped
