Manley Performance Extreme Stroker Pistons

Chrysler 6.1L HEMI 4.060in Bore 1.220in Compression Dome

597860CE-8

Overview:

The Manley Extreme Stroker Piston set is engineered specifically for Chrysler 6.1L HEMI engines, designed to support high-performance builds with a 4.060-inch bore and 1.220-inch compression dome. These pistons are ideal for enthusiasts and professional engine builders seeking durable, precision-forged components that enhance power and reliability in extreme stroker applications.

Crafted from premium 2618 alloy forgings, this set of eight flat top pistons features a -1.5cc dish volume to optimize combustion chamber dynamics and compression ratios. Whether you are building a street performance engine or a race-ready powerplant, these pistons deliver the strength and consistency required for demanding conditions.

Key Features:

Manley’s Extreme Stroker Pistons incorporate advanced materials and design elements to maximize performance and longevity:

• Constructed from 2618 aluminum alloy forgings known for superior strength and thermal resistance under high-stress conditions.
• Proven cam and barrel skirt profiles reduce friction and wear, improving piston stability and engine efficiency.
• Equipped with tool steel wrist pins for enhanced durability and precise fitment.
• Moly skirt coatings on select part numbers reduce friction and protect against scuffing during operation.
• Flat top piston design with a -1.5cc dish volume to optimize compression and combustion for extreme stroker builds.
• Precision machined to exacting tolerances, ensuring consistent performance and reliable fitment in 6.1L HEMI stroker engines.
• Designed to withstand high RPM and boost levels typical in performance and racing applications.

Construction & Design:

These pistons are forged from high-grade 2618 aluminum alloy, a material favored in motorsports for its excellent fatigue resistance and ability to handle elevated temperatures. The cam and barrel skirt profiles have been extensively tested to minimize piston slap and improve ring seal, contributing to longer engine life and smoother operation.

The inclusion of tool steel wrist pins provides a robust connection between the piston and connecting rod, capable of handling the increased loads of stroker configurations. Additionally, the moly skirt coating applied on select pistons reduces friction against the cylinder walls, enhancing durability and reducing wear.

Installation & Fitment:

This piston set is designed as a direct fit for Chrysler 6.1L HEMI engines bored to 4.060 inches with a 1.220-inch compression dome. Installation requires standard engine assembly procedures and is intended for use in stroked engine builds where precise piston-to-cylinder clearance and compression volume are critical.

No special modifications beyond typical engine machining and assembly are required to install these pistons.
