The JE Pistons Mitsubishi 4B11T Custom Piston Set is designed for high-performance applications, offering durability and optimized performance. These pistons are forged from 2618 aluminum, providing high tensile strength suitable for demanding conditions. The proprietary Forged Side Relief (FSR) design minimizes friction and power loss by reducing skirt width and shortening the wrist pin, saving weight and improving efficiency. Depending on the application, these pistons feature a skirt coating to reduce friction, wear, and operating noise, as well as an accumulator groove to improve ring seal and power consistency. The kit includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings. This piston set is specifically designed for the Mitsubishi 4B11T engine with an 86.5mm (3.405") bore, a 10.00:1 compression ratio, and a dome design, making it ideal for performance builds, including racing and motorsports applications.
