Description
If you're building or rebuilding a Twin Cam 88 engine and demand maximum ring seal with minimal piston rock, KB Performance pistons deliver the precision tolerances and material science that separate high-revving reliability from failure. The T-5 heat-treated 390 hypereutectic aluminum construction allows a significantly tighter piston-to-wall fit than conventional pistons, reducing blow-by and extending ring life—critical for forced induction applications and sustained high-RPM operation. These are diamond-machined to plus or minus one gram weight consistency, ensuring balanced combustion and reduced vibration across the entire RPM band.
