KB Performance Forged Piston Kit - 4.125 in. Bore - KB662C-STD
  • 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
