JE Pistons SUB WRX EJ205 79mm STR 93mm Bore CR 9.5 KIT Single Left Piston

Forged from 2618 aluminum, this JE Pistons single piston is built for high-demand performance applications in your Subaru EJ205 stroker engine. JE Pistons has been making forged pistons for over 75 years, and they engineer these specifically for each engine and use case to get the best balance of durability and performance. This piston is designed for a 93mm bore with a 9.5:1 compression ratio.

This piston features JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by using a reduced skirt width. Some applications also include a skirt coating to further reduce friction and wear on the cylinder walls, which can also help quiet down engine noise. An accumulator groove is also included on some applications to help manage combustion gas pressure, reducing ring flutter and improving the seal for consistent power delivery.

This kit includes the high-quality wrist pins, locks, and JE Pro Seal premium piston rings you need to get the job done. All JE Pistons are forged and machined 100% in the USA.
