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

JE Pistons is known for making well-built forged racing pistons, with over 75 years of experience. They've applied that knowledge to this specific piston kit for the FIAT 159A engine. If you're rebuilding the top end of your engine for higher performance, these pistons are built to handle the stress.

These pistons are forged in the USA from 2618 aluminum, which gives them the strong tensile strength needed for demanding applications. They feature JE's proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight. Depending on the specific application, they may also include an accumulator groove to help reduce combustion gas pressure, improving ring seal and keeping power consistent. A skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, while also cutting down on operating noise.

This kit is designed specifically for the 159A engine and includes everything you need to get started: four pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings. They are made 100% in the USA. Please note that this kit is not CARB approved and cannot be shipped to California.
