The King Engine Bearings CR 881SI0.75 is a complete SI-Series connecting rod bearing set engineered for Ford 281ci and 330ci engines. This is a 0.75mm undersize bearing set, designed for use with crankshafts that have been reground to a 0.75mm undersize specification. The bi-metal construction features an aluminum-silicon base layer bonded to a precision steel backing for outstanding strength and wear resistance.

King SI-Series bearings are purpose-built for aftermarket engine rebuilding applications. They are an ideal choice for gasoline or diesel engine rebuilds using OE crankshafts, offering a direct-fit replacement with enhanced performance characteristics over stock bearings.
