The SBC PowerPak F/T Piston 4.040 Bore from MAHLE PISTONS is purpose-built for small-block Chevrolet engines demanding reliability and performance in both street and competition applications. This forged piston is engineered for serious builders and enthusiasts who refuse to compromise on durability when pushing displacement or boost levels.
Whether you're assembling a high-rpm naturally aspirated stroker or preparing for forced induction, the 4.040-inch bore specification delivers the precision fit and structural integrity required for consistent power delivery. Forged construction sets this PowerPak piston apart from cast alternatives, offering superior strength-to-weight ratios critical for sustained high-rpm operation and thermal stability under load.
Professional engine builders and experienced DIY mechanics select this piston for daily-driver reliability as well as bracket-racing and street-performance builds. The 4.040-inch bore size accommodates popular overbore cylinder work and pairs seamlessly with standard rod lengths, making it an ideal choice for both stock-displacement rebuilds and custom-displacement combinations on SBC platforms including 283, 302, 327, and 350 variants.
