About this part

Product Details

Starting with a 2618 alloy forging, these Manley pistons are built for serious performance in your Chrysler Hemi 6.4L engine. They're designed with a -12.5cc dish to help achieve your desired compression ratio, and they come in a 4.100 inch bore size, +.010 inch oversize. This set includes eight pistons, each featuring a 1.210 inch compression height. The choice of 2618 alloy is key here; it's a strong material that holds up well under the stresses of a high-performance engine build.

Manley doesn't stop at the forging. These pistons feature proven cam and barrel skirt profiles, which help them generate power while also being easier on your cylinder walls during operation. The ring lands and grooves are machined to exacting standards, which is critical for a good seal and getting the most power out of your combustion. They also come standard with tool steel wrist pins, known for their strength and durability. If you're rebuilding a Hemi 6.4L and need a solid set of forged pistons that professional engine builders trust, these are a well-built option.

This set is not CARB approved and cannot be shipped to California. Be sure to check all manufacturer installation instructions before beginning your engine build.
