JE Pistons Subaru EJ257 Right Single Piston - 99.75mm Bore - 1.130in. CH -21.10 CC

When you're rebuilding the top end of your Subaru EJ257, this JE Pistons right single forged piston is what you'll want to get the job done right. You get the piston itself, along with high-quality wrist pins, locks, and JE Pro Seal premium piston rings all included in this package. This piston is forged in the USA from 2618 aluminum, which gives it the high tensile strength needed for performance applications where the engine is under a lot of stress.

JE Pistons has been making forged pistons for over 75 years, and they engineer each piston specifically for the engine it's going into. This one is designed for the Subaru EJ257, with a 99.75mm bore and an inverted dome/dish shape. It also features a proprietary Forged Side Relief (FSR) design that helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, which also saves weight. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, while also cutting down on operating noise. An accumulator groove can also be present, which helps reduce combustion gas pressure, improving ring seal for consistent power.

This piston is made 100% in the USA. Please note that this part is not CARB approved and cannot be shipped to California.
