Manley 46364GT-8 4.165" Bore 1.5mm Gas-Nitrided Top Piston Ring Set (8-Pack)

The Manley 46364GT-8 is a high-performance 1.5mm gas-nitrided steel top piston ring designed for a 4.165-inch bore diameter application.

Manley's gas-nitrided top rings feature a hardened surface treatment that dramatically increases wear resistance and reduces friction compared to standard chrome or plain steel rings. The nitriding process creates a tough outer shell that stands up to the extreme combustion temperatures and pressures found in turbocharged, supercharged, and high-compression naturally aspirated applications.

Key Features:

• Bore Size: 4.165 inches
• Ring Width: 1.5mm top ring
• Material: Steel with gas-nitrided surface treatment
• Gas-nitrided face coating for superior wear resistance and hardness
• Designed for high-performance, forced-induction, and racing applications
• Precise tolerances for optimal ring seal and reduced blow-by
• Compatible with Manley and other aftermarket performance pistons at the specified bore size

Manley Performance has been a trusted name in high-performance engine components for decades. These top rings are an ideal choice for engine builders seeking a reliable, race-proven ring solution for 8-cylinder performance builds requiring a 4.165-inch bore specification.
