Manley Performance Premium Steel Ring Set

Chrysler HEMI 6.4L 4.100in Bore

46131ST-8

Overview:

The Manley Performance Ring Set is engineered specifically for Chrysler HEMI 6.4L engines with a 4.100-inch bore. This premium steel ring set is designed to provide reliable sealing and durability under high-performance conditions. Whether you are rebuilding your engine for street use, racing, or heavy-duty applications, these rings help maintain optimal compression and reduce blow-by for improved engine efficiency.

Ideal for performance enthusiasts and professional engine builders, this set supports enhanced power output and longevity by using high-quality materials and precise manufacturing tolerances. The file-fit design allows for custom fitting to ensure the perfect seal and fitment in your engine’s cylinders.

Key Features:

Manley’s ring set offers several technical advantages that contribute to engine performance and reliability:

• Constructed from premium steel for superior strength and wear resistance.
• File-fit design allows precise gap adjustment for optimal sealing and compression.
• Ring dimensions of 1.5mm top ring, 1.5mm second ring, and 3mm oil ring thickness for balanced oil control and compression.
• Designed specifically for 4.100-inch bore Chrysler HEMI 6.4L engines to ensure exact fitment.
• Set includes 8 rings, enough for a complete 4-cylinder piston ring installation.
• Manufactured to tight tolerances to maintain consistent performance under high stress.
• Improves engine efficiency by reducing blow-by and oil consumption.

Construction & Design:

The rings are crafted from high-grade steel alloy, providing excellent resistance to heat and wear commonly experienced in high-performance HEMI engines. The file-fit design means each ring can be carefully matched and adjusted to the cylinder bore, ensuring a perfect seal and minimizing the risk of ring flutter or failure.

This construction supports long-term durability and consistent performance, even under demanding driving conditions such as spirited street driving or track use. The combination of ring thicknesses balances compression sealing with effective oil control to protect your engine’s internals.

Installation & Fitment:

This ring set is designed for professional installation during engine rebuilds or overhauls on Chrysler HEMI 6.4L engines with a 4.100-inch bore. Because it is a file-fit set, careful measurement and gap setting are required to achieve optimal performance and longevity.

• Fits Chrysler HEMI 6.4L engines with 4.100in bore diameter.
• File-fit rings require precise gap measurement and adjustment before installation.
• Compatible with standard piston ring grooves designed for these dimensions.

What’s Included

• Set of 8 premium steel piston rings (1.5mm top, 1.5mm second, 3mm oil rings)

Ideal For:

This ring set is perfect for engine builders and performance enthusiasts who are rebuilding or upgrading Chrysler HEMI 6.4L engines. It suits applications ranging from daily driving to high-performance street and track use where reliable sealing and durability are critical.

• Engine rebuilds and overhauls on 6.4L HEMI engines
• Performance upgrades requiring durable, high-quality piston rings
• Street performance and occasional track use
• Enthusiasts seeking improved compression and reduced oil consumption

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.
