JE Pistons FIAT 159A 9.2:1 KIT Set of 4 Pistons

This JE Pistons kit gives you a complete set of four forged pistons, along with high-quality wrist pins, locks, and JE Pro Seal premium piston rings. These pistons are specifically made for the FIAT 159A engine, featuring a 9.2:1 compression ratio and a 3.425-inch bore. They are designed to handle the demands of performance applications, offering a strong combination of durability and optimized power.

Crafted from 2618 aluminum in the USA, these pistons utilize JE Pistons' proprietary Forged Side Relief (FSR) design. This forging minimizes friction and power loss by reducing skirt width and using a shorter wrist pin, which also saves weight. Depending on the specific application, you might find an accumulator groove to help control 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 can also help quiet down engine noise.

JE Pistons has over 75 years of experience in creating forged racing pistons, and this kit reflects that expertise. They are engineered and machined entirely in the USA, ensuring they meet high standards for performance and longevity. This set is a solid option for anyone rebuilding or upgrading their FIAT 159A engine for more demanding use.
