Manley Chrysler 5.7L Hemi 99.619mm Stock Stroke -3.579in Dome Piston Set

Built from domestic 2618 alloy forgings, these Manley pistons are a solid choice for anyone rebuilding a Chrysler 5.7L Hemi engine. They're designed for a stock stroke of 99.619mm and feature a dome profile, with a bore size of 3.922 inches (99.63mm). The use of 2618 alloy is notable because it offers a great balance of strength and thermal expansion properties, which is crucial for pistons that need to withstand high temperatures and pressures inside the combustion chamber.

Manley doesn't stop at just the material. These pistons come with premium chrome moly wrist pins, and for those looking for even more durability, upgrades to 9310 or Turbo Tuff/DLC alloys are available. The ring lands and grooves are machined to exacting standards, which helps ensure a better seal between the piston rings and the cylinder wall, ultimately leading to more power. You'll also find that Manley's pistons feature proven cam and barrel skirt profiles. This design helps the piston move smoothly within the cylinder, reducing wear on the cylinder walls while still allowing the engine to make substantial power.

What's included are the pistons themselves, along with the standard chrome moly wrist pins. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're building a performance Hemi, these Manley pistons are a well-built option that many professional engine builders trust for their projects.
