Manley Chrysler Hemi 5.7L 3.937in Bore 3.579in Stroke +1.50cc Flat Top Piston Set

If you're rebuilding the heart of your 2005-2008 Chrysler 300 with the 5.7L Hemi engine, this forged piston set from Manley Performance is a solid choice. These pistons are designed with a 3.937-inch bore and a 3.579-inch stroke, featuring a flat top with a +1.50cc volume, making them suitable for various performance builds. They are crafted from domestic 2618 alloy forgings, a material known for its exceptional strength and ability to handle the demands of a high-performance engine.

Manley has incorporated proven cam and barrel skirt profiles into these pistons. This design helps generate more power while also being gentler on your cylinder walls, contributing to longer engine life. The ring lands and grooves are machined to strict standards, which is crucial for achieving a good seal with your piston rings, ultimately leading to more efficient combustion and increased power output. Each set includes premium chrome moly wrist pins for added durability, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, a detail that matters for consistent performance.

This set is designed for direct fitment in the 2005-2008 Chrysler 300, as well as the 2006-2008 Dodge Charger and 2005-2008 Dodge Magnum. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're aiming for improved performance and reliability in your Hemi engine, this Manley piston set offers the robust construction and thoughtful design that professional engine builders trust.
