King Engine Bearings Mazda E3/E5/(Size +1.0mm) Main Bearing Set

Built with a bimetal aluminum base, this main bearing set is made for your 1979-1985 Mazda GLC with an E3 or E5 engine. Main bearings are crucial components that support the crankshaft within the engine block, allowing it to spin smoothly while handling significant loads. This set is specifically sized at +1.0mm, meaning it's designed for engines that have already been machined to a larger size during a previous rebuild or repair.

King Engine Bearings uses a bimetal construction, which combines the strength of steel with the bearing properties of aluminum. This approach helps to manage heat and wear effectively, contributing to the longevity of your engine's rotating assembly. Because these are main bearings, they are a key part of the engine's bottom end, and ensuring they are the correct size and well-made is important for proper oil pressure and crankshaft support.
