JE Pistons MITSU 4G63 2.3L KIT Set of 4 Pistons

If you're building a high-performance Mitsubishi 4G63 engine, this set of four forged pistons from JE Pistons is a solid choice. These pistons are specifically made for the 4G63 engine found in the 2001-2007 Evolution VII-IX models, featuring a 3.366-inch bore and an 8.50:1 compression ratio with an inverted dome/dish design. JE Pistons brings over 75 years of experience to the table, ensuring you get a well-built component designed for demanding applications.

What sets these pistons apart is their construction and design features. They are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for handling the extreme pressures of a performance engine. JE Pistons incorporates their proprietary Forged Side Relief (FSR) design, which helps reduce friction and skirt wear while also saving weight. Depending on the specific application, you might also find an accumulator groove to improve ring seal and reduce flutter, and a skirt coating to further cut down on friction, wear, and noise. This kit comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have the essential pieces for installation.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. For any build pushing the limits of a 4G63, these pistons offer a proven combination of durability and performance, crafted with meticulous attention to detail right here in the USA.
