Overview 

The UEM Piston 1FZ 102/STD Stroke Flat is a high-performance forged piston specifically engineered for Toyota 1FZ-FE engines running a standard stroke crankshaft. With a 102mm bore and flat-top design, it is optimized to deliver increased compression, improved flame propagation, and efficient combustion—ideal for naturally aspirated or lightly boosted setups. The flat-top crown maximizes compression without the need for forced induction, offering enhanced throttle response and overall engine performance. Crafted from high-strength forged materials, this piston is built to withstand the extreme thermal and mechanical demands found in motorsport, off-road, and high-output street applications, ensuring long-lasting durability and reliability.
