JE Pistons - Set of 4 Mitsubishi 4B11T 88.0mm Bore -8.2 Dish Asymmetrical FSR Pistons - Set of 4

If you're rebuilding the engine in your Mitsubishi 4B11T for high-performance use, a solid set of pistons is crucial. These JE Pistons are forged from 2618 aluminum, a material known for its high tensile strength, making them well-suited for demanding applications where durability and consistent performance are key. They are designed specifically for the 4B11T engine, ensuring an optimized fit and function.

JE Pistons uses a proprietary Forged Side Relief (FSR) design on these pistons. This advanced forging minimizes friction and power loss by using a reduced skirt width, and the shorter wrist pin further saves weight. Depending on the specific application, these pistons may also feature an accumulator groove to help reduce combustion gas pressure, which improves ring flutter resistance and maintains a consistent ring seal for reliable power. A skirt coating, also application-dependent, is used to reduce friction and wear on the piston skirts and cylinder walls, contributing to quieter operation and longer engine life. Every component is manufactured 100% in the USA.

This set includes four pistons, each with an 88.0mm bore and a -8.2 dish. You'll also find high-quality wrist pins, locks, and JE's Pro Seal premium piston rings included, so you have the essential pieces to get your engine back together. Please note that these pistons are not CARB approved and cannot be shipped to California.
