Automobile Engine Piston for TOYOTA Auto

The Yiwu Jucheng Auto Parts Co., Ltd. engine piston is manufactured from aluminium alloy AC8A, a cast aluminium-silicon-copper alloy widely used in automotive applications for its high strength-to-weight ratio and thermal conductivity. It covers TOYOTA engine series including 2SZ-FE, 3SZ-FE, 1E-FE, 2E-FE, 3E-FE, 4E-FE, 5E-FE, 3A-FE, 4A-FE, 5A-FE, 7A-FE, 8A-FE, 1ZZ-FE, 3ZZ-FE, 4ZZ-FE, 1GR-FE, 2GR-FE, 3GR-FE, 5GR-FE, 1AZ-FE, 2AZ-FE, 1ZR-FE, 2ZR-FE, 1RZ-FE, 2RZ-FE, 1TR-FE, 2TR-FE, 1NZ-FE, 2NZ-FE, 1FZ-FE, 1KD-FE, 2KD-FE, 1KZ-TE, 3S-FE, 4S-FE, 2Y, 3Y, 4Y, 1C, 2C, 3C, 2L, 3L, 5L, 3B, 11B, 13B, 14B, 15B, 2F, 5S, 5R, 12R and 22R. Each piston undergoes T5 or T6 heat treatment to stabilise dimensions and improve mechanical properties, ensuring durability under high combustion pressures and temperatures.

The AC8A alloy composition typically includes 8-10% silicon, 1-2% copper, 0.5-1% magnesium and trace elements to enhance wear resistance and reduce thermal expansion, a standard for pistons in gasoline engines. The piston’s surface treatment is customisable per customer request, allowing compatibility with specific engine coatings or finishes. Warranty coverage spans 1 year, a common industry standard for aftermarket engine components, while ISO 9001-2008 certification confirms adherence to quality management systems for manufacturing consistency and defect control.

These pistons are designed for OEM replacement in TOYOTA vehicles, catering to importers and distributors sourcing parts for maintenance, repair or engine rebuilding. The broad engine series compatibility reduces the need for multiple part numbers, simplifying inventory for buyers. Trade terms such as MOQ, packaging and lead time are available on request, as these are not specified in the listing. Buyers typically include automotive workshops, spare parts retailers and fleet operators who prioritise reliability and exact fitment for TOYOTA models.
