Product Details

These connecting rod bearings are built with a bimetal construction, featuring an aluminum base. This design is crucial for handling the loads and heat generated within your engine's connecting rod assembly. They are specifically sized at 0.25mm undersize, meaning they are intended for crankshafts that have been machined down by that amount during an engine rebuild or repair. This precise sizing ensures a proper fit and oil clearance, which is vital for lubricating the crankshaft and preventing premature wear.

King Engine Bearings has engineered these bearings for applications like the Mazda MA and VB engines, and they are verified to fit your 1972-1979 Ford Courier, among other Mazda models. The bimetal construction offers good conformability to the crankshaft journal while maintaining strength. Proper installation is key; these bearings are designed to be installed on a machined crankshaft, so ensure your machine shop has prepared the journals to the correct 0.25mm undersize specification.
