What is the purpose of connecting rod bearings?

Connecting rod bearings are a critical component in your engine's rotating assembly. They sit between the connecting rod and the crankshaft, providing a low-friction surface that allows the rod to spin smoothly. This prevents metal-on-metal contact and ensures proper oil flow for lubrication.

What does the '1.00' size mean for these bearings?

The '1.00' designation typically indicates that these bearings are 1.00mm undersize. This means they are intended for use when the crankshaft journals have been machined down by 1.00mm during an engine rebuild. It's important to measure your crankshaft journals to ensure you order the correct bearing size.

Are these bearings sold individually or as a set?

This product is a set of connecting rod bearings. Typically, a set includes all the bearings needed for all the connecting rods in the specified engine.
