JE Pistons FIAT 146A 7.8:1 KIT Set of 4 Pistons

This kit from JE Pistons 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 146A engine, featuring a 7.8:1 compression ratio and a flat-top design with a 3.209-inch bore. They're built to handle the demands of performance applications, whether you're pushing your engine on the track or just want a more robust setup for the street.

JE Pistons uses a proprietary forged side relief (FSR) design, which helps minimize friction and power loss by using a shorter wrist pin and reduced skirt width. This also saves weight. The pistons are forged in the USA from 2618 aluminum, a material known for its high tensile strength, making them well-suited for high-demand performance engines. Depending on the specific application, these pistons may also feature an accumulator groove to help reduce combustion gas pressure, improving ring seal and preventing ring flutter. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

Because these are performance-oriented pistons, they are designed specifically for each engine and use application to offer optimized performance and durability. It's important to note that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
