Ceramic crown treatment, lateral gas ports, Perfect Skirt coating, accumulator grooves, thick-wall wrist pins, double pin oilers, and a premium, carbon-steel ring pack are all part of the winning formula. In addition to the all-star feature list, Ultra Series pistons incorporate a revolutionary, new forging style that strengthens the piston at the material level outward. Grain-Flow Optimization is a breakthrough, and proprietary, piston forging technology and the result of tireless research and development of the in-house JE forging process.
