This kit features JE Pistons' proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width and saving weight with a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove to reduce combustion gas pressure, preventing ring flutter and improving ring seal for consistent power. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which also helps to lower operating noise. This attention to detail means you get pistons that are not only strong but also run smoother and more efficiently.

When you choose this JE Pistons kit, you're getting a complete set of six pistons, including high-quality wrist pins, locks, and JE Pro Seal premium piston rings.
