MAHLE 50514CP.060 Original Engine Piston Ring Set Oversize - 0.060

The MAHLE Original 50514CP.060 is an OE-quality engine piston ring set sized at +0.060" oversize, engineered for engines that have been bored or honed beyond the standard bore diameter. MAHLE is one of the largest OE piston ring manufacturers in the world, and the Original line is built to OE form, fit, and function standards — making it a trusted choice for engine rebuilds and overhauls.

Key Features:

• Without face coating — uncoated ring set designed for applications where a coated ring is not required
• Upper compression ring — cast iron or ductile cast iron with a positive twist and barrel face profile for rapid break-in and efficient compression sealing
• Second (intermediate) ring — provides superior oil control, improved combustion gas management, top ring stability, and sealing to minimize power loss
• CP-20 oil ring assembly — features an exclusive 20-degree ear angle for optimal side sealing against the cylinder wall, plus a chemically polished expander for enhanced oil drain-back
• High tensile strength and high yield strength — delivers stress resistance, minimal groove pound-out, and long service life
• Low ring mass — promotes cylinder bore conformability, reduced friction, good blow-by control, and improved oil economy
• +0.060" oversize — engineered for use with bored or honed cylinders at the 0.060" over standard bore size
