Manley Chrysler 5.7L Hemi 3.917in Bore 4.050in Stroke -23cc Dish Extreme Duty Pistons - Set of 8

If you're building a high-performance 5.7L Hemi engine, especially one that will see serious use or modifications, a strong set of pistons is crucial. These Manley Extreme Duty pistons are built to handle the demands of a performance Hemi, offering a solid foundation for your build.

Crafted from domestic 2618 alloy forgings, these pistons are known for their strength and ability to withstand higher cylinder pressures and temperatures. They feature proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls while still generating power. Manley also pays close attention to the ring lands and grooves, ensuring a tight seal for improved combustion efficiency. The -23cc dish design is specific for certain compression ratio targets in Hemi builds.

This set includes eight pistons, each with tool steel wrist pins for added durability. Manley's unique manufacturing process ensures the ring grooves are perfectly square to the piston skirt, which is important for consistent ring seal. These are a popular choice among professional engine builders for their reliability and performance.
