What does the '.020' in the part number mean?

The '.020' indicates that these piston rings are 0.020 inches undersize. This means they are intended for use with pistons that have been bored out to a slightly larger diameter than the original factory specification, which is common during engine rebuilds.

Are these rings suitable for a standard bore engine?

No, these rings are specifically 0.020 inches undersize. They are designed for engines where the cylinders have been bored out to accommodate this larger ring size, typically during an engine overhaul or rebuild.

What is the benefit of reduced friction and oil consumption?

Reducing friction helps your engine run more efficiently and can lead to slightly improved performance. Minimizing oil consumption prevents excessive burning of oil, which keeps your exhaust cleaner and can save you money on oil top-offs.
