This is a high-performance piston set specifically designed for Toyota 4U-GSE and Subaru FA20 engines. The pistons feature an 86.00mm bore, a 12.5:1 compression ratio, and a -1.0cc dome design. Manufactured using 2618 aluminum alloy for exceptional tensile strength, they are ideal for demanding performance applications. The pistons incorporate a proprietary Forged Side Relief (FSR) design to reduce friction, minimize power loss, and decrease overall weight with a shorter wrist pin and narrower skirt. A specialized skirt coating helps lower friction and wear while reducing operating noise. Some models include an accumulator groove to improve ring seal and maintain consistent power by reducing combustion gas pressure and ring flutter. This set includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, ensuring a complete installation package. Designed for precision and durability, these pistons deliver optimal performance for applications such as racing, drifting, and high-power builds.
