Key Features

• Standard oversize configuration for the listed engine applications
• 3.516-inch bore diameter for matched cylinder fitment
• Carbon steel top and second rings for durable sealing performance

Detailed Description

Mahle 41591CP piston rings are engineered around OE-driven requirements for friction control, oil consumption management, and service life. The ring pack combines 1.50 mm top and second rings with a 4.00 mm oil ring assembly, using a shallow groove layout to match the specified engine design. This part number, 41591CP, is listed for Isuzu Pickup, Amigo, Impulse, and Trooper applications with standard bore sizing. If you are sourcing piston rings for an Isuzu Pickup or related Isuzu engine rebuild, 41591CP provides the material and dimensional details needed for a proper match.

This part cross-references Hastings Piston Rings (e.g., 2C4603) and Sealed Power (e.g., E616KC) for the same application.

What It Is Used For

• Restoring cylinder sealing when compression has dropped
• Reducing oil consumption caused by worn ring packs
• Addressing blow-by from tired piston ring sealing surfaces
• Replacing worn rings during an engine rebuild
• Matching the specified bore and ring dimensions for listed Isuzu engines

Installation Notes and Tips

Verify bore diameter, ring thickness, and groove style before assembly. Confirm the engine is within the listed Isuzu Pickup, Amigo, Impulse, or Trooper fitment range before ordering 41591CP. Clean ring grooves thoroughly and check end gaps during installation to ensure proper sealing.

Quality Assurance

Mahle designs piston rings to OE requirements and focuses on friction reduction, oil control, and long service life. The 41591CP part number reflects premium-grade construction and application-specific engineering.
