The King Engine Bearings MB4272MC.026 is an OE-replacement crankshaft main bearing set designed for the Holden Alloytec 175 and 190 engines. This is the .026mm oversized variant in the MC Series, delivering precise fitment for engines requiring a slight journal oversize.

MC Series Technology:

• Bi-metal construction featuring a steel backing bonded to a strengthened aluminum alloy substrate for superior structural integrity
• K-340 nano-composite polymer coating applied at the factory with no added bearing thickness, preserving exact clearance tolerances
