JE Pistons MITSU 4G63T STRK KIT Set of 4 Pistons

This kit gets you a complete set of four forged pistons from JE Pistons, designed specifically for Mitsubishi 4G63T engines. You'll also find high-quality wrist pins, locks, and JE Pro Seal premium piston rings included, so you have the essential components to rebuild your engine's short block. These pistons are forged in the USA using 2618 aluminum, a material known for its high tensile strength, which is crucial for engines pushed hard in performance applications.

JE Pistons has been a leader in forged racing pistons for over 75 years, and this set reflects that experience. They feature a 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 control combustion gas pressure, leading to better ring seal and consistent power. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise.

These pistons are engineered for each specific engine and use case, aiming for an optimized balance of performance and durability. They are designed for high-demand performance applications, whether you're building for the track or the street. Keep in mind that this kit is not CARB approved and cannot be shipped to California.
