MAHLE 50276CP.060 Standard Piston Ring Set Oversize - 0.060

The MAHLE 50276CP.060 is a standard replacement piston ring set in +0.060" oversize bore sizing, designed for Chrysler/Mopar inline and V8 engines commonly found in classic-era rebuilds. MAHLE Original piston ring sets are engineered to OE tolerances, making them the trusted choice of professional engine builders for over a century.

These rings are pre-lapped at the factory to seat immediately upon installation, virtually eliminating traditional break-in time and getting rebuilt engines up to full operating efficiency faster. Ring materials, coatings, and tension are all optimized for each specific application to reduce friction and extend service life.

Key Features:

• +0.060" Oversize — designed for bores that have been machined 0.060" over standard for worn cylinder rebuilds
• Cast iron or ductile cast iron upper compression rings with positive twist and barrel face for quick, efficient break-in
• Barrel-faced compression ring contact area for improved compression sealing and reduced blowby
• CP-20 oil control ring assembly featuring an exclusive 20-degree ear angle for superior side sealing against the cylinder wall
• Pre-lapped finish for immediate seating — virtually eliminates break-in time
• High tensile and yield strength with low ring mass for stress resistance and minimal groove pound-out
• Optimized ring tension for long service life, oil economy, and low-friction operation
• Manufactured to OE specifications by the world's largest piston ring producer

MAHLE Original piston rings are backed by decades of OE research and development, ensuring each set delivers the dimensional accuracy and metallurgical quality required for a reliable, long-lasting engine rebuild.
