What does 'standard tension' mean for these piston rings?

Standard tension rings apply a consistent, moderate amount of pressure against the cylinder wall. This ensures a good seal for compression and oil control in typical engine operating conditions.

Are these rings suitable for all engine types?

These rings are designed for a specific bore size of 4.320 inches and a standard tension application. Compatibility depends on your engine's specifications and whether this size and tension meet its requirements.

What does 'plain ring' refer to in this product name?

A 'plain ring' typically refers to a ring without special coatings or complex designs, relying on its material and shape for effective sealing. This design is known for its reliability and straightforward performance.
