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 cylinder wall. This helps prevent seizure, lowers operating temperatures, and contributes to quieter engine operation.

Are these pistons suitable for a daily driver or only race cars?

These pistons are designed and built to withstand heavy to severe duty performance applications and race builds. While they can be used in a performance-oriented daily driver, their primary design focus is on extreme durability and power handling for racing.

What is included in this piston kit?

This kit includes a set of four forged pistons, each with a bore size of 84.25 mm. It also includes the necessary ring grooves and features for proper installation and performance. Please refer to the manufacturer's specifications for a complete list of included components.

Product Details

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance applications. The 84.25mm bore size is a common upgrade for Honda B16A engines looking to increase displacement and power. This material choice is key for improved tensile strength, which is crucial when dealing with the higher cylinder pressures found in performance builds.

Wiseco has included several features to ensure durability and performance under demanding conditions. The pistons have precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. This helps maintain compression and prevent blow-by, even in severe duty race applications. The crown is fully machined for accuracy, and the pistons feature forced pin oiling to keep the wrist pins lubricated. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly.

This set includes four pistons, designed to fit Honda B16A engines. They are intended for heavy to severe duty race builds where reliability and strength are paramount. Please note that these pistons are not CARB approved and cannot be shipped to California.
