What is the main purpose of piston rings?

Piston rings have two main jobs: they seal the combustion chamber to maintain compression and power, and they scrape excess oil off the cylinder walls to prevent it from entering the combustion chamber.

Do I need anything else to install these piston rings?

When rebuilding an engine, you'll typically need to replace other wear items such as bearings, gaskets, and seals. Always refer to the manufacturer's service manual for a complete list of parts and procedures.

What does 'standard bore' mean for these rings?

Standard bore means these rings are sized for cylinders that have not been machined or enlarged beyond their original factory diameter. If your engine's cylinders have been bored out, you would need an oversized set.
