JE Pistons Small Block Ford (20 Degree Head) 4.155 Bore / 1.230 CD / 0.927 Pin - Set of 8

If you're building a high-performance Small Block Ford engine, especially one with 20-degree cylinder heads, you're going to need a solid set of pistons. These JE Pistons are forged from 2618 aluminum, a material known for its high tensile strength, making them well-suited for the demands of racing and serious performance applications. They are designed specifically for each engine and use, ensuring you get optimized performance and durability.

JE Pistons uses a proprietary Forged Side Relief (FSR) forging design that helps minimize friction and power loss by reducing skirt width. This design, along with a shorter wrist pin, also helps save weight. Depending on the specific application, these pistons may also feature an accumulator groove to help reduce combustion gas pressure, which can prevent ring flutter and improve ring seal for more consistent power. Some applications also include a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down operating noise. Every set is forged and machined 100% in the USA.

This set includes eight pistons, each with a 4.155-inch bore and a 1.230-inch compression distance, designed for a 0.927-inch pin. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're looking for pistons that have been proven on the track and built for serious performance, this set from JE Pistons is a strong option.
