JE Pistons MITSU 4G63 94STR KIT Set of 4 Pistons

If you're rebuilding the engine in your 2001-2007 Mitsubishi Lancer Evolution, these JE Pistons 4G63 94STR KIT piston sets are a solid choice for serious performance. JE Pistons has been making forged pistons for over 75 years, and they build these specifically for each engine application, like the 4G63. They're forged and machined right here in the USA using 2618 aluminum, which gives them the strong tensile strength you need when you're pushing your engine hard.

What sets these apart is their design. They use a proprietary Forged Side Relief (FSR) forging, which helps reduce friction and skirt width to save weight. Some applications also get an accumulator groove to help with ring seal and an inverted dome or dish shape for optimized combustion. Plus, a skirt coating can be included to cut down on friction and noise. You'll get a set of four pistons, along with high-quality wrist pins, locks, and JE's Pro Seal premium piston rings, all made in the USA.

This kit is designed for a 3.346-inch bore and includes a 0.866-inch pin. Keep in mind these pistons are not CARB approved and cannot be shipped to California. They are intended for high-demand performance applications where durability and optimized power are key.
