JE Pistons MITSU 4G63T STRK KIT Set of 4 Pistons

JE Pistons has been a leader in forged racing pistons for over 75 years, applying that experience to a wide range of applications. This piston set is specifically made for the Mitsubishi 4G63T engine, a popular choice for performance builds. These pistons are engineered to provide a strong combination of durability and performance, whether you're building for the track or the street.

These pistons are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for high-demand performance engines. They feature JE Pistons' proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin for weight savings. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, improving ring seal and preventing flutter. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down engine noise.

This set is designed specifically for the 4G63T engine, with a bore size of 3.366 inches and a 22mm pin. The kit includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, ensuring you have the essential components for installation. Please note that these pistons are not CARB approved and cannot be shipped to California.
