Installation Notes and Tips

Verify bore size, groove dimensions, and engine configuration before installation. Clean the ring lands thoroughly and confirm ring end gaps to the engine builder’s specifications. This part cross-references Monroe Shocks & Struts (e.g., 495P, E442X) for the same application.

Quality Assurance

Use this piston ring set only where the listed fitment and bore specifications match the engine. Confirm compatibility with the exact engine build before assembly.
