JE Pistons SUB EJ25 DOHC 8.5:1 KIT Set of 4 Pistons

If you're building a high-performance Subaru EJ25 DOHC engine, getting the right pistons is crucial. This JE Pistons kit is designed to handle the stress of demanding builds, offering a solid foundation for serious power. These pistons feature an 8.5:1 compression ratio, making them suitable for forced induction applications where you need to manage boost and heat effectively.

JE Pistons uses a proprietary Forged Side Relief (FSR) forging design, which helps reduce friction and skirt wear, especially important in high-RPM situations. They're forged from 2618 aluminum right here in the USA, a material known for its high tensile strength, necessary for engines pushing the limits. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and consistent power delivery. Some applications also feature a skirt coating to further reduce friction and noise.

This kit comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have the essential components needed for installation. Remember, these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
