What does 'file-fit' mean for these piston rings?

File-fit rings are not pre-gapped to a specific cylinder bore size. You'll need to carefully file the ends of the rings to achieve the correct gap for your engine's cylinders during installation. This allows for a precise fit tailored to your build.

What are the benefits of the carbon steel nitride and iron ferroxide materials?

Carbon steel nitride is used for the top and oil rings for its durability and sealing properties. The iron ferroxide second ring is chosen for its compatibility and sealing characteristics within the cylinder bore, contributing to overall engine efficiency.

Are these rings suitable for all engine builds?

These rings are designed for engine builds where precise sealing and horsepower maximization are key. However, they are not CARB approved and cannot be shipped to California. Always consult your engine builder or mechanic for specific component recommendations.
