Mahle MS Piston Set SBC 408ci 4.165in Bore 3.75in Stroke 6.0in Rod .927 Pin 11cc 14.5 CR Set of 8

Crafted from 2618 aluminum alloy, these Mahle MS pistons are built for serious performance in your Chevrolet Small Block engine. With a 4.165-inch bore and a 3.75-inch stroke, they're designed to create a robust 408 cubic inch displacement, offering a significant increase in power potential. The 11cc dish volume, combined with a 6.0-inch rod length and a .927-inch pin, helps achieve a strong 14.5:1 compression ratio, ideal for naturally aspirated or forced induction applications where maximum power is the goal.

Mahle's expertise in piston design is evident in these forged components. Forging the aluminum alloy creates a stronger, more durable piston than cast alternatives, allowing them to withstand the higher cylinder pressures and temperatures common in performance builds. This set includes everything needed for an 8-cylinder engine, ensuring a complete solution for your engine rebuild. The precise machining and material selection mean these pistons will fit right and perform reliably under demanding conditions.

When rebuilding a performance Small Block Chevrolet, choosing the right internal components is crucial. These Mahle pistons are a solid option for those looking to maximize displacement and compression for significant horsepower gains. Please note that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or Mahle's technical documentation for specific assembly and tuning recommendations to get the most out of this high-performance piston set.
