The ISUZU 4HK1 crankshaft (8-98029270-5)is made from high-quality 40Cr alloy steel and enhanced through a specialized induction hardening process, forming a 3–5 mm surface layer with a hardness of up to HRC 52–58. Compared to nitrided cast iron, this treatment improves wear resistance by 15%. Even under high load and harsh engine conditions, it maintains excellent performance and extended service life, making it an ideal choice for engine repair and replacement.
