JE Pistons MITSU 4G63 EVO KIT Single Piston

Forged from 2618 aluminum, these JE Pistons are built for the demands of performance Mitsubishi 4G63 Evolution VII-IX engines from 2001-2007. This material choice is key because it offers the high tensile strength needed when you're pushing an engine hard, whether that's on the track or just in spirited street driving. JE Pistons has been making performance parts for a long time, and they engineer these pistons specifically for the 4G63 engine to balance durability with optimized performance.

You'll find some well-thought-out design features here. The proprietary Forged Side Relief (FSR) design helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, which also saves a bit of weight. Depending on the specific application, you might also find a skirt coating to further reduce friction and wear, leading to quieter operation. An accumulator groove is also included on some applications to help manage combustion gas pressure, which improves ring seal for more consistent power delivery.

This kit comes with everything you need to get these pistons installed: high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. They are made 100% in the USA, so you know you're getting a well-built part designed for serious performance.
