Mahle Ford 6.4L 4.134in Stroke 6.929in Rod Perf Pistons

These Mahle performance pistons are built for the Ford 6.4L Powerstroke engine, featuring a 4.134-inch stroke and a 6.929-inch connecting rod length. The 1.516-inch wrist pin diameter is a common size for this application, and the -39.7cc dish volume contributes to a 16.3:1 compression ratio, suitable for performance builds where enhanced power and torque are desired.

Crafted from cast aluminum, these pistons are designed to handle the increased demands of a performance engine. Each piston weighs in at 773 grams, a specification that helps maintain proper rotating assembly balance. The 3.886-inch bore size is standard for the 6.4L Powerstroke, and the 2.049-inch compression height ensures correct piston-to-valve clearance and deck height when paired with the specified stroke and rod length.

This set is intended for engine builders looking to upgrade their 392 cubic inch Powerstroke. 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.
