Description

Created from a high-silicon aluminum alloy, KB Performance pistons are lightweight to improve throttle response and RPM changes while still being strong enough to withstand high compression and high temperatures. Each piston is engineered with race ready features like high upper compression-ring locations, gas-accumulator grooves, drilled oil returns, and spiral-lock retainer grooves.
