What does '1.0mm undersize' mean for these bearings?

This means the bearings are manufactured to be slightly smaller than the standard size by 1.0 millimeter. They are intended for use when the connecting rod journals on the crankshaft have been machined down (ground undersize) during an engine rebuild or repair.

What is a bimetal bearing?

A bimetal bearing uses a combination of materials, typically a steel backing for strength and an aluminum-based alloy overlay for good bearing performance. This construction helps manage heat and provides a solid surface for the rotating crankshaft journal.

Do these bearings come with installation instructions?

While this set is designed as a direct fit, it is always recommended to refer to the manufacturer's installation guidelines or a service manual for the proper procedure when installing engine bearings.

You're getting a set of connecting rod bearings designed to fit your 1972-1979 Ford Courier. These are bimetal bearings, meaning they have an aluminum base, which is a common and well-built material for engine components.

The bimetal construction helps manage heat and wear within the engine's rotating assembly, ensuring proper lubrication and support for the connecting rods.
