• Precision-machined ring grooves and an anti-detonation groove improve ring seal and reduce the risk of detonation.
• ArmorGlide skirt coating reduces friction, prevents seizure, and promotes quieter piston operation.
• Fully machined crown design enhances combustion efficiency and power output.
• Forced pin oiling system ensures consistent lubrication for the wrist pins under severe duty cycles.
• Designed and manufactured in the USA to strict quality standards.
• Includes premium piston rings optimized for racing and high-performance use.
• Compression height of 33.25 mm and bore size of 88.50 mm tailored for the 2AZ-FE engine.
• Pin diameter of 0.866 inches for precise fitment and durability.

Construction & Design:

Wiseco’s Professional Series pistons are crafted from high-grade 2618 aluminum alloy, known for its superior strength and thermal resistance compared to standard piston materials. The forging process enhances the metal’s grain structure, resulting in pistons that can endure the rigors of racing and high-performance driving.

The ArmorGlide skirt coating is a specialized treatment that minimizes friction between the piston and cylinder wall, reducing wear and improving engine efficiency. Additionally, the pistons feature a fully machined crown and precision ring grooves that contribute to better combustion and ring sealing, which are critical for maintaining power and reliability under demanding conditions.

Installation & Fitment:

This piston set is designed as a direct fit for the following vehicles:

• Scion tC Base (2005–2010)
• Scion tC Spec (2007–2008)

The pistons are engineered to match the factory bore and compression specifications, ensuring straightforward installation in compatible 2AZ-FE engines. No modifications to the engine block or additional machining beyond standard rebuild practices are typically required when installing this kit.
