What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide skirt coating on these Wiseco pistons is designed to reduce friction between the piston skirt and the cylinder wall. This helps to prevent seizure under high temperatures and loads, while also contributing to quieter engine operation.

Are these pistons suitable for a street-driven vehicle?

These are Wiseco's Professional Series pistons, engineered for heavy to severe duty race builds and extreme performance applications. While they can be used in modified street vehicles, their design is optimized for the demands of racing and may require specific tuning and supporting modifications for optimal performance and longevity.

What does the -8.00 CC dish volume signify?

The -8.00 CC dish volume refers to the shape and depth of the piston crown. This specific dish volume is designed to work with certain cylinder head combustion chamber designs to achieve a desired compression ratio for high-performance LS engines.
