• Pistons forged from 4032 aluminum alloy
• Forged 4032 alloy is an 1% silicon alloy that is formed in a forging press then fully machined
• The combination of this alloy and forging process allows the piston to flex under detonation or preignition, giving the best resistance to cracking
• Since 4032 alloy has a low expansion rate but higher than Hypereutectic, it will require about a .001 in. wider piston to wall clearance
• Forged pistons are suited for Street or Race with power adders such as NOS or boost
• Feature an anti-friction skirt coating
• Offset pin design for quiet operation
• Each kit contains 2 pistons, pins, spiral-lock pin clips and Hastings moly rings
