Mahle 42289CP Engine Piston Ring Set

Engine Piston Ring Set Overview

Mahle 42289CP is a premium engine piston ring set built for standard bore applications with a 3.1102-inch bore diameter. It is engineered around low-friction ring technology to help control oil consumption and support longer service life in compatible engines.

Compatible with Ford Escape, Ford Fiesta, Ford Transit Connect, Ford Fusion, Chevrolet Aveo, Pontiac G3, and Chevrolet Aveo5 applications listed below, this Mahle piston ring set uses a stainless steel top ring, cast iron second ring, and a GNS-coated oil ring assembly for a technical OE-style replacement. Part number 42289CP is also cross-referenced to Hastings Piston Rings 2C4199 for the same application.

Installation Notes and Tips

Verify bore diameter, ring thickness, and shallow groove requirements before installation. Confirm the engine application against the fitment list for your Ford Escape, Ford Fusion, or Chevrolet Aveo project, and inspect cylinder condition, ring end gaps, and groove cleanliness during assembly. Follow the engine builder’s service procedures for ring orientation and break-in.

Quality Assurance
