KB Performance Pistons have everything you want in a performance piston: the strength to withstand high compression and heat, lightweight design, and a price that fits your budget. Most are forged from high-silicon aluminum alloy, then CNC-machined and heat-treated for strength up to 30% greater than stock. They’re also engineered with race-ready features like high upper compression-ring locations, gas-accumulator grooves, drilled oil returns, and spiral-lock retainer grooves. We also carry Keith Black Silv-O-Lite pistons for high quality in a lower-silicon stock replacement piston.
