Product Details

This is a set of connecting rod bearings for your Mazda MA, VB, or Ford Courier engine. These bearings are made with a bimetal construction, featuring an aluminum base, which is a common and well-built material for engine components. They are sized 0.50mm undersize, meaning they are intended for use when the crankshaft journals have been machined down by that amount during an engine rebuild.

King Engine Bearings is a well-known name in engine components, and these bearings are designed to fit right into your engine. They are a solid option if you're rebuilding the bottom end of your engine and need to replace worn-out bearings or account for crankshaft machining.
