JE Pistons FA20 - 4UGSE 9.5:1 KIT Set of 4 Pistons

Built from 2618 aluminum, these JE Pistons are forged in the USA for high-demand performance applications. They're specifically designed for the FA20 engine, aiming for an optimized balance of performance and durability. The 9.5:1 compression ratio is a solid choice for many performance builds, offering a good compromise between power and pump gas compatibility.

JE Pistons uses a proprietary Forged Side Relief (FSR) forging design. This design helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, which also saves weight. 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, if included for this application, further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down operation.

This kit includes everything you need to get your engine rebuilt: four pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings. These are a well-built option for anyone looking to upgrade their FA20 engine for more demanding use. Please note that these pistons are not CARB approved and cannot be shipped to California.
