What does 'narrowed' mean for these rod bearings?

A narrowed bearing has a slightly reduced width compared to a standard bearing. This extra clearance is often necessary when using aftermarket connecting rods that are wider than stock, or for specific engine builds where clearance is critical.

Are these bearings suitable for a stock engine rebuild?

While these are Race Series bearings built for performance, they can be used in a stock rebuild if you're looking for a well-built, durable option. However, their primary design is for engines that will see higher RPMs and increased stress.

What is the advantage of ceramic bearings?

The input data does not specify that these bearings are ceramic. These are ACL Race Series bearings, known for their advanced materials and construction for high-performance applications, but the specific material composition beyond 'advanced' is not detailed.
