Mahle MS Piston Set Hemi 392ci 3.927in Bore 4.05in Stroke 6.125in Rod .927 Pin -2cc 9.3 CR Set of 8

If you're building or rebuilding a high-performance Hemi engine, especially a 392 cubic inch stroker, a solid set of pistons is crucial. This Mahle MS Piston Set is designed for those demanding builds, offering the strength and precision needed to handle increased power and stress. These pistons are compatible with both 5.7L and 6.1L Hemi heads, giving you flexibility in your engine configuration.

Mahle has engineered these pistons from a strong 4032 aluminum alloy, known for its good thermal expansion properties and durability, which is important for managing heat in a performance engine. They feature a 3.927-inch bore and are designed to work with a 4.050-inch stroke and a 6.125-inch connecting rod, with a .927-inch pin. The -2.2cc valve relief volume contributes to a 9.3:1 compression ratio when used with compatible heads and a 4.050-inch stroke, striking a good balance for streetable power and performance. Each piston weighs in at approximately 405 grams, helping to keep rotating assembly weight manageable.

This set includes eight pistons, ready for your 392 Hemi build. Please note 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.
