Mahle MS Piston Set SBC 395ci 4.030in Bore 3.875in Stroke 6.0in Rod .927 Pin -5cc 11.4 CR Set of 8

This Mahle MS Piston Set includes eight forged pistons, designed for a Chevrolet Small Block 395 cubic inch engine. Each piston features a 4.030-inch bore, a 3.875-inch stroke, and is intended for use with a 6.0-inch connecting rod and a 0.927-inch wrist pin. These pistons are crafted from 4032 aluminum, a well-known material for its strength and durability in high-performance applications. The dish volume is -5cc, contributing to a calculated compression ratio of 11.5:1 with the specified components. Each piston weighs approximately 406 grams, indicating a robust construction suitable for demanding engine builds.

Mahle has engineered these pistons with a focus on performance and reliability. The 4032 aluminum alloy offers good thermal expansion properties, which helps maintain consistent piston-to-wall clearance across a range of operating temperatures. This is crucial for preventing piston slap and ensuring efficient power delivery. The -5cc dish volume is specifically designed to achieve a target compression ratio, making these pistons a solid choice for builders aiming for a specific performance outcome in their SBC engine. The inclusion of eight pistons means you have a complete set ready for a V8 engine rebuild.

When considering this piston set, it's important to note that they are not CARB approved and cannot be shipped to California. Additionally, this product is subject to California's Proposition 65 warning. Ensure all supporting engine components, such as connecting rods, crankshaft, and cylinder heads, are compatible with these specifications to achieve the intended performance and compression ratio. Proper installation and balancing are key to maximizing the longevity and performance of these Mahle pistons.
