Construction & Design:
JE Pistons utilizes premium 2618 T6 forged aluminum alloy, known for its exceptional tensile strength and resistance to thermal fatigue, making it ideal for extreme performance environments. The pistons feature smooth flowing radii on the dome and dish areas to promote efficient flame travel and combustion. Each piston is manufactured using state-of-the-art CNC machines to maintain tolerances within millionths of an inch, ensuring consistent performance and reliability.
The full round skirt design enhances piston stability within the cylinder bore, reducing noise and wear. The included carbon steel wrist pins and wire locks provide secure and durable wrist pin retention, critical for high-RPM and boosted applications.
Installation & Fitment:
This piston set is a direct fit for the 2AZ-FE engine found in 2005–2010 Scion tC and 2008–2015 Scion xB2 models. Installation requires standard engine disassembly and machining to accommodate the 0.5mm oversized pistons. No additional modifications or deburring of the dome/dish surfaces are necessary, simplifying the build process. Professional installation is recommended to ensure proper clearances and ring end gap settings for optimal performance and longevity.
What's Included:
- Set of forged 2618 T6 aluminum pistons (4 pistons)
- Piston rings (1.0 x 1.2 x 2.8 mm widths)
