JE Pistons FA20 - 4UGSE 10.5:1 KIT Set of 4 Pistons

JE Pistons is known for making well-built forged pistons that have proven themselves on the race track for over 75 years. This piston kit is specifically made for the FA20 engine, offering a 10.5:1 compression ratio. These aren't just generic pistons; they're engineered and machined in the USA using 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines pushed to their limits.

What sets these pistons apart is their advanced design features. The proprietary Forged Side Relief (FSR) forging design helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, which also saves weight. Depending on the specific application, you might find an accumulator groove, which helps manage combustion gas pressure to prevent ring flutter and improve the seal for consistent power. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down engine noise. These pistons are designed specifically for the FA20 engine and its intended use, aiming for optimized performance and durability.

This kit comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have the essential components needed for installation. Remember, these pistons are not CARB approved and cannot be shipped to California. They are made 100% in the USA, ensuring you're getting a product built with a focus on quality and performance.
