Description
The pistons feature a proprietary Forged Side Relief (FSR) design, which minimizes friction and power loss through a reduced skirt width. They also incorporate a shorter wrist pin to save weight. Depending on the application, skirt coating may be included to reduce friction and wear, and an accumulator groove can help reduce combustion gas pressure for improved ring seal.
