SPEED PRO Pistons and Rings and Ring Kits

Speed-Pro ring sets feature plasma-moly faced ductile top rings for nearly instant ring seating. Second rings are designed to aid in oil control and intentionally allow an escape path for any combustion gases which get past the top ring. The famous SS-50U oil ring is the absolute best proven design for controlling oil and is available in low tension versions for increased horsepower potential.
