JE Pistons SUBEJ22 TRB91-94 KIT Set of 4 Pistons

If you're building a high-performance Subaru EJ Series engine, this JE Pistons SUBEJ22 TRB91-94 KIT set of four pistons is a solid choice. JE Pistons has been making forged pistons for over 75 years, and they build these specifically for racing applications, whether you're on the drift track or the drag strip. They're made in the USA from 2618 aluminum, which gives them the high tensile strength needed for demanding performance builds.

What sets these pistons apart is their proprietary Forged Side Relief (FSR) design. This helps minimize friction and power loss by reducing skirt width, and the shorter wrist pin also saves weight. Depending on the specific application, you might also find an accumulator groove, which helps reduce pressure from combustion gases to improve ring seal and prevent fluttering. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which also helps quiet down the engine. This kit comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have everything you need to get them installed.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. They are designed for specific engine and use applications to give you optimized performance and durability.
