MAHLE 41612.020 Engine Piston Ring Set

The MAHLE 41612.020 is a precision-engineered engine piston ring set designed to meet or exceed OEM specifications. MAHLE is a globally recognized manufacturer of engine components trusted by OEM factories and professional rebuilders alike, known for delivering consistent sealing performance, oil control, and long service life.

This piston ring set features a .020" oversize bore diameter, making it the correct choice for engines that have been bored 0.020" over the standard size during a rebuild. Using the proper oversize rings ensures optimal ring-to-wall contact, compression retention, and oil control in a freshly honed cylinder bore.

Key Features:

• OEM-quality materials for reliable compression sealing
• Precision ground profiles for optimal ring-to-wall contact
• 0.020" oversize (.020 over standard bore)
• Includes compression rings and oil control ring assembly per cylinder
• Engineered for consistent performance across the full RPM range
• Manufactured to MAHLE's strict dimensional tolerances

MAHLE piston rings are produced using high-strength cast iron and steel alloys with surface treatments such as chrome, nitride, or phosphate coatings depending on ring position and application, providing superior wear resistance and reduced break-in time. This set is suited for professional engine rebuilds where precision fitment is critical.
