310321

Overview:

The JE Pistons 2AZFE Pistons Kit is a premium forged piston set designed specifically for the 2005 to 2010 Scion tC equipped with the 2AZ-FE 4-cylinder engine. Backed by over 75 years of expertise in forged racing pistons, JE Pistons delivers a product engineered for durability and high-performance applications. Whether you are building a street-driven engine or a race-ready powerplant, this piston kit offers the strength and precision needed to handle demanding conditions while maximizing engine efficiency and power output.

Manufactured entirely in the USA, these pistons are crafted to exacting standards to ensure optimal fitment and performance. If you want to upgrade your engine’s internals with components trusted by racers worldwide, this JE Pistons kit is an excellent choice for enhancing reliability and power delivery.

Key Features:

This piston kit incorporates advanced design and manufacturing technologies to provide superior performance and longevity:

• Proprietary Forged Side Relief (FSR) forging design reduces friction and power loss by minimizing skirt width and shortening the wrist pin length, resulting in weight savings and improved efficiency.
• Accumulator groove (application dependent) reduces combustion gas pressure on piston rings, minimizing ring flutter and improving ring seal for consistent power output.
• Skirt coating (application dependent) lowers friction and wear between piston skirts and cylinder walls, while also reducing operating noise for smoother engine operation.
• Forged from high-strength 2618 aluminum alloy in the USA, providing excellent tensile strength to withstand high-performance and high-demand engine conditions.
• Engineered specifically for the 2AZ-FE engine to optimize performance and durability tailored to this application.
• Includes premium JE Pro Seal piston rings, high-quality wrist pins, and locks to ensure a complete, ready-to-install piston kit.
• Dome piston design with an 11.00:1 compression ratio and a 3.504-inch bore size, ideal for performance tuning and power gains.

Construction & Design:

Each piston in this kit is forged, machined, and finished 100% in the USA, reflecting JE Pistons’ commitment to quality and precision. The use of 2618 aluminum alloy provides the necessary strength and durability for high-revving and high-stress environments typical of performance engines. The Forged Side Relief (FSR) design reduces skirt contact area to minimize friction and power loss, while the accumulator groove helps maintain ring stability under combustion pressure. Additionally, the optional skirt coating enhances wear resistance and reduces noise, contributing to longer engine life and quieter operation.

Installation & Fitment:

This piston kit is designed as a direct replacement for the factory pistons in the 2005–2010 Scion tC with the 2AZ-FE engine. It fits precisely to OEM specifications, ensuring a straightforward installation process without the need for modifications. No cutting, drilling, or special tuning is required to install these pistons, making them suitable for engine builders and enthusiasts looking for a reliable upgrade.

What’s Included
