MAHLE 4605MS-15 Performance Piston Ring Set 4.600" Bore 1.5mm 1.5mm 3.0mm File Fit

The MAHLE 4605MS-15 is a high-performance piston ring set designed for 4.600-inch bore engines with a +0.005-inch oversize tolerance. This 8-cylinder ring set features metric ring widths of 1.5mm top compression ring, 1.5mm second compression ring, and 3.0mm oil control ring in a file-fit configuration for precise end gap adjustment.

Key Features:

• 4.600-inch bore diameter with +0.005-inch tolerance
• File-fit design allows custom end gap fitting for optimal sealing
• 1.5mm/1.5mm/3.0mm metric ring widths
• Engineered using advanced piston ring simulation technology
• Designed to minimize friction and unlock "free" horsepower
• Ultra-flat ring flanks maximize ring-to-piston sealing
• Complete 8-cylinder set included

MAHLE Performance piston rings are developed using pioneering computer simulation tools to reduce friction losses while maintaining excellent cylinder sealing. The file-fit design allows engine builders to precisely gap each ring to their specific bore dimensions and operating conditions. Whether building a high-performance street engine or race application, MAHLE's motorsport-grade piston rings deliver proven durability and performance.
