Keith Black Forged Pistons

keith black pistons for evolution engines

When building a high performance engine you want to use the very best. Keith Black Forged Pistons are an excellent choice. KB Performance pistons are a Forged 4032 low expansion alloy. The 4032 alloy is preferred for high performance / high compression applications. They offer offset wrist pins for a quiet running engine. The low expansion alloy allows for a tighter piston to wall running clearance which lets the piston rings do their job better. This means better compression with less blow-by and better oil control to keep oil out of the combustion chamber. The cleaner the charge, the better it burns, the more power you have. :?)
