    KB Performance Forged Piston Kit - 4.00 in. Bore (w/Screamin Eagles 95cc Heads)

    • 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
