JE Pistons SUB EJ25 SOHC 11.5:1 KIT Set of 4 Pistons

JE Pistons is known for making strong, reliable forged pistons that have proven themselves on the race track for over 75 years. This specific kit is for Subaru EJ25 SOHC engines and is designed to handle high-demand performance applications. They are forged in the USA using 2618 aluminum, which gives them the high tensile strength needed for serious builds.

This set of four pistons features JE's proprietary Forged Side Relief (FSR) design. This helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, improving ring seal and keeping power consistent. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, while also cutting down on operating noise. These pistons are designed specifically for the EJ25 engine to give you optimized performance and durability.

When you get this kit, you'll find everything you need to get started. It includes high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. Remember, this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
