What material are these pistons made from?

These Wiseco pistons are forged from 2618 aluminum. This material is chosen for its improved tensile strength, making it well-suited for high-performance and heavy-duty engine applications.

What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide coating on the piston skirts serves multiple purposes. It helps reduce friction between the piston and cylinder wall, resists seizure under extreme conditions, and contributes to quieter operation.

Are these pistons suitable for all engine builds?

These pistons are specifically designed and built to withstand heavy to severe duty performance applications and racing builds. They are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

Forged from 2618 aluminum, these Wiseco pistons are built for serious racers and builders who need a strong, reliable component for heavy to severe duty engine builds. The 3.940-inch bore size is specific for Chrysler 318 applications, and the 1.460-inch compression height is a key measurement for setting up your engine's valve timing and quench. Wiseco machines these pistons in the USA, ensuring precision throughout the manufacturing process.

You'll find features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements designed to keep combustion contained and power up. The crown is fully machined for a clean combustion chamber, and they include forced pin oiling to keep the wrist pins well-lubricated under high stress. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit when you're pushing an engine hard.

This set includes eight pistons, ready for your next performance engine build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
