Manley Chrysler 6.4L Hemi 4.090 Bore -20.5cc Dish Stroker Series Piston Set

Manley Performance has a solid reputation for building robust engine components, and their Stroker Series pistons are a prime example of that commitment. If you're building a high-performance 6.4L Hemi engine, especially for stroker applications, these pistons are designed to handle the demands. They feature a 4.090-inch bore and a -20.5cc dish, which is crucial for setting up your compression ratio correctly when you're increasing displacement.

These pistons are forged from domestic 2618 alloy, a material chosen for its exceptional strength and ability to perform under high stress. Manley also incorporates proven cam and barrel skirt profiles, which help manage piston rock and reduce wear on your cylinder walls while still allowing the piston to generate substantial power. The ring lands and grooves are machined to exacting standards, ensuring a tight seal for improved combustion efficiency and more power. For added durability, they come standard with premium Chrome Moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the piston skirt, which is vital for consistent ring seal.

When you're investing in a stroker build for your 6.4L Hemi, using pistons from a trusted name like Manley means you're starting with a strong foundation. These are the kind of parts that professional engine builders and tuners rely on for both performance and long-term durability. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
