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

If you're rebuilding the engine in your Subaru EJ25 SOHC, this JE Pistons kit is built for serious performance. These aren't your average pistons; they're forged from 2618 aluminum right here in the USA, giving them the high tensile strength needed for demanding applications. JE Pistons brings over 75 years of experience to the table, ensuring these pistons are designed specifically for your engine to offer the best balance of durability and power.

This kit features JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and reduce weight by using a narrower skirt and a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and consistent power. Some applications also include a skirt coating that further reduces friction and wear on the cylinder walls, while also quieting down the engine operation. This set includes everything you need to get your engine rebuilt: the four pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings.

Keep in mind that this kit is not CARB approved and cannot be shipped to California. For a complete engine rebuild, ensure you have all necessary supporting components and refer to the manufacturer's installation instructions for proper assembly.
