Product Details
This is a Mahle file fit piston ring set, designed for engine rebuilding. The rings measure 3.571 inches in bore size and are file-fit, meaning you'll adjust the end gap to match your specific cylinder bore. This set includes three rings per piston: two compression rings measuring 1.5mm thick and one oil control ring at 3.0mm thick. The +.005 inch designation indicates they are slightly oversized for a worn cylinder bore.
Mahle is a well-known name in engine components, and these rings are built for a solid fit and function. File-fit rings are often chosen when a precise end gap is critical for optimal compression and oil control, especially in performance or custom engine builds. This approach allows mechanics to dial in the fit for a particular engine's needs, ensuring good sealing against the cylinder wall.
Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine's service manual for proper installation procedures and specifications.
