ACL Mazda B6/BP/BP-T 1.6/1.8L .50mm Oversized High Performance Main Bearing Set

The ACL 5M8353H-.50 high performance main bearing set is designed for Mazda B6, BP, and BP-T 1.6L and 1.8L engines requiring .50mm oversized main bearings. Manufactured for performance-oriented engine builds and precision rebuilds, this set supports reliable crankshaft operation and consistent bearing performance under demanding conditions.

ACL main bearings are engineered with attention to material strength, load capacity, oil control, and dimensional accuracy.

Fitment includes Mazda Protege model years from 1990 through 1996 and select 2001-2002 Kia Rio applications. Vehicle compatibility can vary by engine configuration and prior machine work, so confirm the engine code and required bearing size before ordering.
