• ArmorGlide skirt coating reduces friction and minimizes wear on cylinder walls
• Heavy-duty (HD) design built to withstand severe-duty racing and extreme engine conditions
• Deep valve pockets accommodate oversized valves and high-lift camshafts
• Complete kit includes premium piston rings, wrist pins, and retaining clips
• Forged in the USA at Wiseco's state-of-the-art facility in Mentor, Ohio

Wiseco's Professional Series pistons represent the pinnacle of piston engineering, designed for serious racers and engine builders who demand no-compromise performance. The forging process compresses the aluminum's molecular structure, increasing density and aligning grain flow for exceptional strength, impact resistance, and fatigue life. The lower compression ratio helps prevent detonation under high boost conditions, allowing for aggressive tuning while maintaining engine reliability. Each piston is precision-machined using advanced CNC equipment and features offset pins for quieter operation, just like OEM specifications.
