Wiseco Professional Series Forged Pistons
2005–2010 Scion tC (2AZ-FE Engine)
K641M895
Overview:
The Wiseco Professional Series forged piston kit is engineered for serious racers and high-performance builders who demand durability and precision. Designed specifically for the Scion tC models from 2005 to 2010 equipped with the 2AZ-FE engine, these pistons offer a reliable upgrade for heavy to severe duty race applications. With premium rings included, this set of four pistons helps you push your engine’s limits while maintaining strength and efficiency under extreme conditions.
Whether you are building a track-focused engine or a high-output street machine, Wiseco’s Professional Series pistons deliver the performance and resilience needed to withstand intense combustion pressures and high RPM operation.
Key Features:
These pistons incorporate advanced design and manufacturing technologies to ensure optimal performance and longevity:
- Forged from high-strength 2618 aluminum alloy, providing superior tensile strength and durability compared to cast pistons.
- Precision-machined ring grooves and an anti-detonation groove enhance ring seal and reduce the risk of detonation for improved combustion efficiency.
- ArmorGlide skirt coating reduces friction, resists seizure, and promotes quieter piston operation under high stress.
- Fully machined piston crowns with a -29cc reverse dome design optimize combustion chamber shape for improved power and efficiency.
- Forced pin oiling system increases lubrication to the wrist pin area, reducing wear and extending piston life.
- Compression height of 33.25 mm and pin diameter of 0.866 inches ensure precise fitment and compatibility with factory components.
- Set includes four pistons, perfectly matched for balanced engine performance.
Construction & Design:
Wiseco’s Professional Series pistons are engineered and machined in the USA with meticulous attention to detail. The use of 2618 aluminum alloy offers excellent fatigue resistance and thermal conductivity, essential for racing and high-performance engines. The ArmorGlide skirt coating minimizes friction between the piston and cylinder wall, reducing wear and improving engine efficiency. The reverse dome crown design helps control compression ratio and combustion dynamics, making these pistons ideal for forced induction or high-compression naturally aspirated builds.
Installation & Fitment:
This piston kit is designed as a direct fit replacement for the Scion tC equipped with the 2AZ-FE engine from 2005 through 2010, including the Spec trim from 2007 to 2008. The pistons maintain stock bore size at 89.50 mm and are compatible with factory rods and rings, facilitating a straightforward installation process for experienced engine builders.
No modifications to the engine block or connecting rods are typically required when installing this kit, but professional machining and assembly are recommended to ensure optimal performance and reliability.
What's Included:
- Set of 4 forged pistons with -29cc reverse dome crowns
