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

JE Pistons is known for making well-built forged racing pistons, with over 75 years of experience. They've applied that knowledge to this specific piston kit for Subaru EJ25 SOHC engines. These aren't just off-the-shelf parts; they're engineered for your engine to give you a solid combination of durability and performance, whether you're on the track or just pushing your car hard.

This kit uses a proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight. Depending on the specific application, you might also find an accumulator groove to help manage combustion gas pressure, leading to better ring seal and consistent power. Some applications also include a skirt coating to further cut down on friction and wear, which also helps quiet things down. These pistons are forged in the USA from 2618 aluminum, a strong material that can handle the demands of high-performance engines. They're designed specifically for the EJ25 SOHC engine to give you optimized performance and durability.

This kit includes everything you need to get these pistons installed: high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details regarding installation procedures and any required hardware.
