• Piston crown designed and machined to retain optimal direct injection function, yet still achieve a 10.0:1 compression ratio

• Aligned Grain Flow forging process done in-house in the USA provides unmatched tensile strength characteristics, perfect for high-horsepower builds

• Thermal Barrier Ceramic crown coating reflects heat and protects piston crown from potential damages of excess combustion temperatures

• Perfect Skirt coating reduces operating friction and noise

• Lateral gas ports paired with 1.0mm x 1.2mm x 2.8mm ring package promote power through consistent ring seal

• Supplied with robust, 9310 steel, .210” wall wrist pins and available in standard, .015” overbore and .025” overbore bore size options
