These pistons incorporate JE's proprietary Forged Side Relief (FSR) design, which uses a reduced skirt width to minimize friction and power loss while also saving weight. Depending on the specific application, you might also find an accumulator groove to help manage combustion gas pressure, leading to better ring seal and consistent power delivery. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise. This kit comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have the essential components for installation.
