Mahle MS Piston Set Hemi 6.4L 392ci 4.095in Bore 3.724in Stroke 6.200in Rod 11:1 CR Set of 8

When you're rebuilding the heart of your Hemi 6.4L 392ci engine, you're getting a full set of eight Mahle MS forged replacement pistons. These are designed as a drop-in assembly, meaning they're built to fit right into your existing engine configuration without needing major modifications. Mahle is a well-known name in engine components, and this set is crafted for those who demand reliable performance from their build.

Each piston in this set features a 4.095-inch bore and a 3.724-inch stroke, with a 6.200-inch rod length. They're designed to achieve an 11:1 compression ratio, which is a solid bump over stock for improved power output. The pistons are made from 4032 aluminum, a material known for its strength and durability, especially under high temperatures and pressures. The pin size is 0.945 inches, and each piston weighs in at approximately 454 grams, contributing to a well-balanced rotating assembly. The 3.6cc dish volume helps achieve that 11:1 compression ratio with the correct cylinder head volume.

This piston set is a substantial upgrade for anyone looking to get the most out of their 392 Hemi. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a successful rebuild, always refer to the manufacturer's detailed installation instructions and torque specifications.
