Forged in the USA from 2618 aluminum, Ultra Series pistons combine application-specific engineering with thermal barrier crown coating, coated skirts, lateral gas ports, and high-strength 9310 alloy wrist pins. The crown coating helps manage heat at the piston, while the skirt coating reduces friction and wear. Lateral gas ports support top-ring sealing under demanding cylinder pressures, and the FSR forging keeps the design focused on strength and reduced reciprocating weight. Supplied with piston rings, this kit provides a complete set of four pistons for a serious street, track, or competition
