Description
If you’re building a high-revving engine that demands precision and durability, KB Performance pistons are engineered for tighter tolerances and longer service life than standard alternatives. The T-5 heat-treated 390 hypereutectic aluminum construction allows you to run tighter clearances, reducing piston rock and improving ring seal—critical factors for consistent power delivery and reduced blow-by. Whether you’re assembling a street machine or race engine, these diamond-machined pistons hold weight and dimensional tolerances so tight that you get measurable gains in reliability and performance.
