Manley Chrysler 5.7L Hemi 90.9mm Stock Stroke 3.917in Bore 9.3cc Extreme Duty Dome Piston Set

Manley Performance is well-known for making strong engine components that professional builders trust. If you're working on a Chrysler 5.7L Hemi and need a robust piston set, their Extreme Duty Dome Pistons are a solid choice. These are built for demanding builds, offering a significant step up from stock in terms of strength and performance.

These pistons start with domestic 2618 alloy forgings, which are chosen for their superior strength compared to cast aluminum. They feature a dome design with a 9.3cc volume, intended to work with the stock stroke and a 3.917-inch bore. Manley also uses proven cam and barrel skirt profiles, which help the piston move smoothly in the cylinder bore, reducing wear and noise while still allowing for good power output. The ring lands and grooves are machined to strict standards, which is key for getting a good seal from your piston rings, leading to better compression and more power.

Included with these pistons are premium chrome moly wrist pins, known for their durability. Manley's manufacturing process uses unique fixturing that allows them to machine the skirt and cut the ring grooves in a single operation. This ensures the ring grooves are perfectly square to the piston skirt, which is critical for optimal ring seal and overall engine health. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
