What does the '+1.0mm' mean on this bearing set?

The '+1.0mm' indicates that these bearings are designed for crankshaft main journals that have been machined down by 1.0 millimeter. This is common during engine rebuilds when the original journals have wear or damage and need to be ground undersize.

What is the material of these main bearings?

These bearings feature a bimetal construction with an aluminum base. This type of material is chosen for its good wear characteristics and compatibility with crankshafts in many engine applications.

Do these bearings come with installation instructions?

While installation instructions are not typically included with bearing sets, it is critical to follow the specific service manual for your vehicle's make and model. This will detail the proper cleaning, installation, and torque procedures.
