AZ9231320743 HC16 rear axle differential assembly is OEM reinforced heavy-duty rear axle middle section exclusively designed for Sinotruk HC16 tandem rear drive axles with a fixed 5.73 gear ratio. The thickened integrated reducer housing precisely controls internal assembly clearances, effectively preventing abnormal running noise, persistent oil leakage and gear tooth breakage under full-load bumpy working conditions. Every finished rear axle section passes bench running-in inspection and hydraulic sealing pressure testing before delivery. We supply OEM matching genuine equivalent spare parts and premium aftermarket assemblies, covered by a 6-month quality warranty for bulk export orders to global heavy truck spare parts wholesalers.
