What is the purpose of the -15cc reverse dome dish?

The -15cc reverse dome dish is a key feature for tuning your engine's compression ratio. It helps lower the compression when used with certain cylinder heads and head gaskets, which is often necessary for high-performance or forced induction applications.

Are these pistons suitable for a daily driver?

These are Wiseco Professional Series pistons, engineered and built for heavy to severe duty race applications. While they are well-built and durable, they are optimized for extreme performance and may not be the ideal choice for a standard daily driver due to their design and intended use.

What does the ArmorGlide skirt coating do?

The ArmorGlide skirt coating is applied to reduce friction between the piston skirt and cylinder wall. This helps prevent seizure, lowers operating temperatures, and contributes to quieter piston operation, especially under high-stress conditions.

Product Details

This is a set of eight Wiseco Professional Series forged pistons designed for Chevrolet LS engines with a 4.080 inch bore. These pistons feature a -15cc reverse dome dish, which is crucial for setting your compression ratio, especially when paired with specific cylinder heads and head gasket thickness. They are built from 2618 aluminum, a well-known material for its improved tensile strength, making them suitable for heavy to severe duty performance builds where durability under extreme conditions is paramount.

Wiseco machines these pistons in the USA, ensuring precision in every detail. You'll find precision ring grooves, anti-detonation grooves, and features designed to improve ring seal, all contributing to better combustion efficiency and power. The crown is fully machined for accuracy, and they incorporate forced pin oiling to keep the wrist pin lubricated under high stress. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit during high-RPM operation.

This set is intended for serious racers and builders who are pushing their LS engines hard. Because these are performance pistons, it's important to note they are not CARB approved and cannot be shipped to California. You'll want to ensure you have the correct supporting components, like appropriate connecting rods and a balanced rotating assembly, to match the demands these pistons are built to handle.
