This Mahle MS Piston Set gives you everything you need to rebuild the heart of your Chevy Small Block engine for a 440 cubic inch displacement. Inside this set, you'll find eight forged pistons, each designed with a 4.185-inch bore and a 4.00-inch stroke. These pistons are built to work with a 6.0-inch connecting rod and feature a .927-inch pin diameter. The dish volume is 6.0cc, which, combined with the other dimensions, results in a 14.5:1 compression ratio for a powerful build. Each piston weighs in at 444 grams, contributing to a well-balanced rotating assembly.

Mahle is known for its well-built engine components, and these pistons are no exception. They are constructed from 2618 aluminum, a material chosen for its strength and ability to withstand the high temperatures and pressures found in performance engines. This material choice helps ensure durability and consistent performance over time. The precise machining and design of these pistons are crucial for optimal engine operation, helping to seal the combustion chamber effectively and transfer power efficiently. When you're aiming for a significant displacement increase and a higher compression ratio, using pistons from a reputable manufacturer like Mahle is a solid choice for reliability.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures to ensure the best results for your engine build. Proper balancing of the rotating assembly is also critical when installing new pistons.
