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

Starting with a 2618 aluminum forging, these JE Pistons for your 1999 or 2001 Ford Mustang are built for serious performance. They feature an inverted dish design with a -17.0cc volume and a 3.552-inch bore, specifically made to optimize your SBF 4.6L 4V engine. JE Pistons has been making forged racing pistons for over 75 years, and these are engineered and machined entirely in the USA to handle the demands of high-performance applications.

The design includes a proprietary Forged Side Relief (FSR) forging, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight in the process. Depending on the specific application, you might also find an accumulator groove to help manage combustion gas pressure, leading to better ring seal and more consistent power. Some applications also feature a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also quieting down operation. This attention to detail in materials and design means you're getting a well-built piston set that’s ready for the track or the street.

This set includes eight pistons, each designed for a specific engine and use. Remember that these pistons are not CARB approved and cannot be shipped to California. If you're rebuilding the top end of your Mustang's 4.6L 4V engine for enhanced performance, this set from JE Pistons is a solid option.
