Description

Silvolite Pistons improve power, fuel economy, cylinder sealing, service life and cost effectiveness by significantly reducing expansion rate, allowing the piston to be run with reduced clearance. 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.
