JE Pistons SBF 4.6L 4V DISH Set of 8 Pistons

If you're rebuilding the engine in your 1999 or 2001 Ford Mustang for serious performance, JE Pistons offers a well-built set of forged pistons designed for the SBF 4.6L 4V engine. These pistons are crafted from 2618 aluminum, a material known for its high tensile strength, making it ideal for high-demand applications where durability and consistent performance are critical. Each piston features an inverted dish design with a 3.552-inch bore and a -17.0cc volume, which is important for setting your compression ratio correctly.

JE Pistons brings over 75 years of experience to their forged piston designs, and these are no exception. They are forged and machined entirely in the USA, ensuring a high level of manufacturing control. Features like the proprietary Forged Side Relief (FSR) design help minimize friction and reduce weight by using a narrower skirt and a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, improving ring seal and maintaining consistent power output. Some applications also benefit from a skirt coating that further reduces friction and noise while protecting the piston skirts and cylinder walls.

This set includes eight pistons, the wrist pins, and locks, ready for installation. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For optimal results, always refer to the manufacturer's installation instructions and ensure all related components are properly matched for your specific build.
