KB Performance Forged Piston Kit - 4.010 in. Bore - KB661C-010

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
