KB Performance Pistons

KB Performance hypereutectic pistons are made from 390 aluminum alloy and heat-treated to T6 standards, which makes them 30 percent stronger than ordinary untreated hypereutectics. Their 100 percent CNC-machined crowns, high upper compression-ring location, gas-accumulator groove, drilled oil returns, and spiral-lock retainer grooves make these pistons outstanding for performance applications. They have a lightweight, rigid-rib skirt design that stabilizes the piston in the bore. All of this adds up to pistons that fit tighter than forged types, provide improved oil control, reduce blow-by, increase ring life, eliminate cold start-up knocking, and won't cost you an arm and a leg! Thousands of models are available—find the set and options designed for your vehicle and engine application.
