JE Pistons Toyota 1FZ-FE STRK KIT 100mm Bore 154mm Rod -17.1cc Dome - Set of 6

If you're rebuilding the engine in your Toyota 1FZ-FE for serious performance, a set of forged pistons is a critical component. This JE Pistons kit is built to handle the demands of high-output applications, offering a significant upgrade over stock cast pistons. They are forged in the USA from 2618 aluminum, a material known for its high tensile strength, making it well-suited for engines pushed beyond their original limits.

JE Pistons has incorporated several design features to optimize performance and durability. The proprietary Forged Side Relief (FSR) forging design helps reduce friction and skirt wear, which can also save a bit of weight. Depending on the specific application, these pistons may also feature an accumulator groove to help reduce combustion gas pressure, improving ring seal and maintaining consistent power. A skirt coating, if included for your application, further reduces friction and noise while minimizing wear on the cylinder walls. This kit includes everything you need to get started: the set of six pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings.

This kit is designed specifically for the 1FZ-FE engine, featuring a 100mm bore and a 154mm rod length with an inverted dome dish that results in an 8.5:1 compression ratio. Please note that this kit is not CARB approved and cannot be shipped to California. For optimal results, always refer to the manufacturer's installation instructions and consult with a professional engine builder.
