What is the compression height and pin diameter for these pistons?

These Wiseco pistons have a compression height of 1.110 inches and use a 0.866-inch pin diameter. This information is important for calculating your engine's final compression ratio.

Are these pistons suitable for a street-driven vehicle?

These pistons are part of Wiseco's Professional Series, designed for heavy to severe duty race builds. While they offer exceptional durability, they are intended for high-performance applications and may not be ideal for a standard street-driven vehicle without other supporting modifications.

What does the ArmorGlide skirt coating do?

The ArmorGlide skirt coating on these pistons is designed to reduce friction between the piston skirt and cylinder wall. This helps prevent seizure, lowers operating temperatures, and contributes to quieter engine operation.

This set of eight forged pistons from Wiseco is designed to handle the demands of severe duty builds, offering improved strength and durability over stock components.

These pistons are forged and machined in the USA from 2618 aluminum, a material known for its high tensile strength, making them well-suited for the stresses of racing. They feature precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. Wiseco also applies an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. The fully machined crown ensures consistent performance and reliability for your engine build.

This set includes pistons with a 4.090-inch bore and a 1.110-inch compression height, utilizing a 0.866-inch pin diameter. They are designed with forced pin oiling for better lubrication. Please note that these pistons are not CARB approved and cannot be shipped to California.
