Mahle MS Piston Set BBC 510ci 4.31in Bore 4.375in Stroke 6.385in Rod .990 Pin 18cc 10.5 CR Set of 8

These Mahle MS forged pistons are built for serious Big Block Chevy builds, specifically for the 511 cubic inch displacement. They feature a 4.310 inch bore and are designed to work with a 4.375 inch stroke crankshaft and a 6.385 inch connecting rod, utilizing a standard 0.990 inch wrist pin. The 18cc dome volume, combined with other engine components, helps achieve a 10.5:1 compression ratio, which is a popular choice for street/strip applications where improved power is desired without sacrificing too much drivability.

Crafted from 4032 aluminum alloy, these pistons are well-built for the demands of a performance engine. This material offers a good balance of strength and lighter weight compared to cast pistons, and it has a lower expansion rate, making it suitable for tighter piston-to-wall clearances. Each piston weighs in at approximately 530 grams, contributing to a balanced rotating assembly. This set includes eight pistons, ensuring you have everything needed for a complete engine rebuild.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. Additionally, they are subject to California's Prop 65 warning. When planning your build, ensure all components are compatible and consider consulting with a professional engine builder to confirm this piston set meets your specific performance goals and application requirements.
