Mahle MS Piston Set SBC 388ci 4.060in Bore 3.750stk 6.125in Rod .0927in Pin -2cc 11.6 CR Set of 8

Mahle's MS Piston Set is built for Small Block Chevy engines aiming for a 388 cubic inch displacement, featuring a 4.060-inch bore and a 3.750-inch stroke. These pistons are crafted from 4032 aluminum, a material known for its strength and ability to handle higher compression ratios and temperatures, making them a solid choice for performance builds. The lightweight design, weighing in at 370 grams, helps reduce reciprocating mass, which can lead to improved engine response and durability under stress.

This set includes pistons with a -2cc valve relief dish, designed to work with a 6.125-inch connecting rod and a 0.0927-inch pin. The specific dish volume contributes to an 11.6:1 compression ratio when paired with the correct cylinder head volume, offering a notable bump in power over stock configurations. Mahle has engineered these pistons for a direct fit in Chevrolet Small Block 362 cubic inch applications, ensuring that installation is straightforward for those rebuilding or upgrading their engine's top end.

It's important to note that these pistons are not CARB approved and cannot be shipped to California due to emissions regulations. For builders outside of California, this Mahle piston set offers a well-built foundation for a high-performance Small Block Chevy engine, balancing strength, weight, and compression for improved output.
