The Wide Journal design is a must have for your high performance RB30 engine build. Born out of necessity, we created the Wide Journal crankshaft in order to combat the well documented big end issues that plague the OEM width big end bearing. By widening the crank pin, we alleviate the pressure that is put on the big end bearing, minimising the chances of premature big end wear and failure. This also enables tuners to be open and aggressive with their tuning strategies, reducing the need to adjust their tuning to accommodate the standard bearing. These cranks were an instant success, producing a multitude of world records.
Nitto 4340 and EN40B 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 or EN40B billet steel crankshaft will rev faster and cleaner due to the different harmonics produced from the high grade material.
Of course, this range does not stop at 4340 crankshafts. Nitto EN40B billet steel crankshafts are manufactured from high quality true billet round bar stock. EN40B crankshafts are manufactured in order to target the highest level of performance in drag racing and circuit racing. With a higher tensile strength than 4340 billet crankshafts, EN40B cranks have the ability to yield greater power and longevity which is critical for any sort of racing or exceptionally high performance application. So, for your high performance engine, we have the ultimate crankshaft to suit your RB30.
