JE Pistons Toyota 1FZ-FE 100.0mm Bore 10.0:1 CR 5.7cc Dome Piston Kit - Set of 6

JE Pistons has been a leader in forged racing pistons for over 75 years, and they've applied that experience to their extensive line of forged pistons for import engines. This specific kit is built for the Toyota 1FZ-FE engine, giving you a solid foundation for a high-performance build. They're engineered and machined entirely in the USA, using 2618 aluminum, which provides the high tensile strength needed for demanding applications. This material choice means you're getting a well-built piston that can handle the stress of serious performance use.

What sets these pistons apart is their specific design for the 1FZ-FE. They feature a proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, saving weight in the process. Depending on the application, you might also find an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and consistent power. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which also helps quiet down the engine's operation. This kit includes everything you need to get started: high-quality wrist pins, locks, and JE's Pro Seal premium piston rings.

This piston kit is designed for a 100.0mm bore and has a 10.0:1 compression ratio with a 5.7cc dome. It's important to note that this kit is not CARB approved and cannot be shipped to California. If you're rebuilding the top end of your 1FZ-FE for serious performance, this set of six forged pistons from JE Pistons is a well-made option.
