What material are these Mahle pistons made from?

These Mahle pistons are constructed from 4032 aluminum alloy. This material is chosen for its strength and durability, making it well-suited for high-performance engine applications where heat and stress are significant factors.

What is the compression ratio achieved with these pistons?

These pistons are designed to achieve an 11:1 compression ratio. This is a common ratio for performance builds, offering a good balance for naturally aspirated or boosted engines.

Are these pistons compatible with all Hemi 6.4L engines?

This set is specifically designed for the Hemi 392 cubic inch (6.4L) engine with a 4.100-inch bore. While it's a direct replacement assembly, it's always best to confirm your engine's exact specifications and intended use with your engine builder to ensure perfect compatibility.

Product Details

This is a set of eight Mahle forged pistons designed for the Hemi 6.4L (392 cubic inch) engine. If you're rebuilding or upgrading your Hemi, these pistons are built to handle the demands of a high-performance engine. They are a direct replacement assembly, meaning they are intended to fit within the stock configuration of the engine, simplifying installation compared to custom setups.

Mahle uses 4032 aluminum alloy for these pistons, which is known for its strength and durability, especially at higher temperatures. This material choice helps ensure the pistons can withstand the increased stress and heat generated in a performance Hemi. The pistons feature a 4.100-inch bore and a 3.724-inch stroke, with a 6.200-inch rod length, and are designed to achieve an 11:1 compression ratio. This compression ratio is a popular choice for naturally aspirated or forced induction builds, offering a good balance between power and drivability.

Each piston weighs 456 grams and includes a 0.945-inch wrist pin. The set comes with everything needed to replace all eight pistons in your Hemi engine. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and torque procedures when installing performance engine components.
