JE Pistons SUBEJ22 TRB91-94 KIT Set of 4 Pistons

When you're rebuilding your Subaru EJ Series engine for serious performance, a solid set of pistons is key. This kit from JE Pistons gives you four forged pistons, designed specifically for your engine. They're made from 2618 aluminum, a strong material that can handle the high stresses of performance applications. JE Pistons has been making forged pistons for over 75 years, and these are forged and machined right here in the USA.

What sets these pistons apart is their design. They feature JE's proprietary Forged Side Relief (FSR) forging, which helps reduce friction and power loss by using a shorter wrist pin and a narrower skirt. Some applications also include an accumulator groove, which can help reduce combustion gas pressure, leading to better ring seal and more consistent power. Depending on your specific application, these pistons may also come with a skirt coating to further reduce friction and wear on the cylinder walls, while also quieting down the engine. This kit comes complete with high-quality wrist pins, locks, and JE's Pro Seal premium piston rings, so you have everything you need to get them installed.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For any other state, this kit offers a well-built foundation for a high-performance engine build.
