Forged Alloy Piston

KB PISTONS Forged Alloy Piston KB PISTONS Forged Alloy Pistons are high-performance 4032 forged pistons engineered for street and race use. Constructed from 4032 alloy with 11% silicon , these pistons deliver superior strength, controlled thermal expansion, and precise dimensional stability for high-output engines and forced-induction applications. Key Features 4032 forged alloy (11% Si) — improved fatigue strength and reduced thermal growth Crack and detonation resistance — optimized grain structure for durability under extreme conditions High-pressure forging + full CNC machining — consistent ring lands and tight tolerances Engineered for forced-induction & nitrous — ideal for turbo, supercharger, and NOS builds Low-friction skirt coatings (select models) — reduced wear and quieter operation Balanced for weight & strength — supports high RPMs and sustained track duty Performance Benefits These pistons combine optimized metallurgy and precision manufacturing to improve heat management, reduce piston-to-wall variance, and extend service life. Builders and engine tuners specify KB pistons for reliable performance when increasing boost, adding aggressive camshafts, or constructing long-life race engines. Applications: street performance, track racing, forced-induction engines, high-output rebuilds, nitrous-assisted builds.
