• ArmorGlide skirt coating reduces friction, resists seizure, and promotes quieter piston operation.
• Fully machined crown with a -29cc reverse dome shelf design tailored for the 2AZ-FE engine.
• Forced pin oiling system enhances wrist pin lubrication under high-stress conditions.
• Pin diameter of 0.866 inches and compression height of 33.25 mm ensure proper fitment and performance.
• Set of one piston designed for sport compact applications, ideal for performance builds.
• Engineered and manufactured in the USA to meet rigorous quality standards.

Construction & Design:

Each Wiseco Professional Series piston is forged and machined with precision to withstand the demands of racing and high-performance engines. The use of 2618 aluminum alloy provides excellent strength and fatigue resistance, essential for engines subjected to high RPM and boost levels.

The ArmorGlide skirt coating minimizes friction between the piston and cylinder wall, reducing wear and improving efficiency. The piston’s fully machined crown features a reverse dome design with a -29cc volume, optimized for the Scion tC’s 2AZ-FE engine to support high compression and combustion efficiency.

Additional design elements such as the anti-detonation groove and enhanced ring sealing features contribute to improved combustion stability and durability under severe operating conditions.
