Chrysler 5.7L HEMI 3.937in Bore .020in Oversize
PIST-3.937/100mm/1.220 CD/DOME E/D
Overview:
The Manley Chrysler 5.7L HEMI Extreme Duty Dome Piston Set is engineered for enthusiasts and professional engine builders seeking enhanced durability and performance in their builds. Designed specifically for the 5.7L HEMI engine with a 3.937-inch bore and .020-inch oversize, these pistons provide a precise fit and reliable operation under demanding conditions.
Built from high-quality 2618 alloy forgings, this piston set offers superior strength and resistance to high temperatures and stress, making it ideal for high-performance street, track, or racing applications. Whether you are upgrading your engine for increased power or rebuilding for longevity, these pistons deliver consistent performance and durability.
Key Features:
Manley’s Extreme Duty Dome Pistons incorporate advanced materials and design features to ensure optimal performance and reliability:
Construction & Design:
These pistons are meticulously crafted using 2618 alloy, a high-strength aluminum alloy known for its excellent fatigue resistance and ability to handle elevated temperatures common in high-performance engines. The forged construction provides superior structural integrity compared to cast pistons, reducing the risk of failure under extreme conditions.
The cam and barrel skirt profiles have been refined through extensive testing to optimize piston-to-cylinder wall contact, reducing friction and wear. Additionally, the moly skirt coating applied on select pistons further enhances durability by providing a low-friction surface that resists scuffing.
Tool steel wrist pins add another layer of strength, ensuring reliable connection between the piston and connecting rod even under high RPM and load scenarios. The dome shape of the piston crown is designed to improve combustion chamber dynamics, contributing to efficient power delivery.
Installation & Fitment:
This piston set is engineered specifically for Chrysler 5.7L HEMI engines requiring a 3.937-inch bore with a .020-inch oversize. It is ideal for engine rebuilds or performance upgrades where precise bore sizing is critical. Installation requires professional engine building expertise to ensure proper clearances and fitment.
No modifications to the engine block are necessary beyond the standard boring and honing process to the specified oversize. Proper assembly and balancing are recommended to maximize performance and longevity.
What's Included:
Ideal For:
Manley Performance manufactures high-strength engine internals for serious builds—especially forged pistons, connecting rods, valves, and valvetrain components developed for racing and high-output street applications. If you’re building for boost, high compression, or sustained RPM, Manley is a common choice for parts engineered to take abuse and keep power reliable.
