Description

Upgrade your Mitsubishi 4B11T engine with the JE Pistons Part Number 317837, a high-performance forged piston set designed for serious enthusiasts and professional racers. Crafted from 2618 aluminum in the USA, these pistons offer a perfect blend of strength and lightweight construction to withstand demanding conditions. The set includes four pistons, each engineered with JE’s proprietary Forged Side Relief (FSR) forging design that reduces friction and minimizes power loss through a narrower skirt profile and a shorter wrist pin, enhancing both efficiency and durability. The pistons feature an inverted dome/dish configuration with a 9.00:1 compression ratio, optimized for high-performance applications and tuning flexibility.Designed specifically for the Mitsubishi 4B11T engine with an 88.0mm bore, these pistons incorporate an accumulator groove (application-dependent) that helps reduce pressure from combustion gases, leading to improved ring seal and consistent power delivery. The skirt coating (application-dependent) minimizes friction and wear on the piston skirts and cylinder walls, while also reducing operating noise for smoother engine operation. Each piston is equipped with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, ensuring reliable sealing and performance under high-stress conditions. Made entirely in the USA, these pistons are built to meet the demands of both street and race environments, providing a significant boost in durability and power potential.Ideal for engine builders seeking maximum performance and longevity, these JE Pistons are engineered for specific engine and application needs.
