Description

Diamond's all new 5.8L Trinity Shelby Series Pistons feature a much taller compression height to bring the Piston closer to the deck. This drastically improves combustion efficiency and flame travel while allowing the rings to be spaced out for additional strength. These Pistons are designed to be used with the factory Plasma Transfer Wire-Arc liner.
