Anatomy Of A Better Piston

Anti-Setonation Grooves Reduces detonation by tempering pressure spikes, enhances piston life!
Pressure Equalization Channel Enhance ring seal, producing more power and enhancing fuel economy!
Slotted Drain Back Holes Slotted drain back holes prevent oil from collecting in the oil ring groove.
CNC Diamond Pinhole Finish Produces ultra straight pinholes and outstanding micro finish for extended life and durability.
Slotted Pin Oiling Slotted pin oiling enhances wrist pin and pin holes oiling for durability and long life.
CNC Diamond Skirt Finishing Retains oil on the piston skirt providing superior anti scuffing capability! Also reduces piston noise!
Ultra-Tight Running Clearance Increases piston and piston ring life and reduces blow by!
Precision Forged of Aircraft Alloy Aluminum Our forgings are approximately 75% stronger than hypoeutectic or hypereutectic castings!
Fully CNC Machined Domes and valve reliefs are fully CNC machined for consistency and precise clearance to valves and combustion chambers.
