Manley Dodge Hemi 6.4L 4.100 Inch Bore 1.75cc Dome Extreme Duty Piston Set

If you're building a high-performance Dodge Hemi 6.4L engine, these Manley Extreme Duty pistons are a solid choice. They're designed for serious builds where durability and power are key. The 4.100-inch bore size and 1.75cc dome volume are specific to certain Hemi engine configurations, so make sure they match your build plans.

Manley uses domestic 2618 alloy forgings for these pistons, which means they're exceptionally strong and can handle the high stresses of a performance Hemi. They also feature proven cam and barrel skirt profiles. This design helps the piston move smoothly in the cylinder, generating power while also being easier on your cylinder walls. The ring lands and grooves are machined to very tight tolerances, which is crucial for getting a good seal with your piston rings. A good ring seal means more consistent compression and better overall engine performance.

These pistons come with premium chrome moly wrist pins, known for their strength. For even more demanding applications, Manley offers upgrades to even tougher alloys. Manley's manufacturing process is also notable; they use unique fixturing that allows them to machine the skirt and cut the ring grooves in one operation. This ensures the ring grooves are perfectly square to the piston skirt, which further contributes to a solid ring seal and reliable operation under load. Keep in mind these are not CARB approved and cannot be shipped to California.
