Mahle Rings Perf Oil Ring Assembly 4.045in x 2.0MM .113in RW Std Tension Chrome Ring Set

When you're rebuilding the bottom end of your engine, getting the piston rings seated properly is key to good compression and oil control. This standard tension oil ring assembly from Mahle OE is designed for a 4.045-inch bore, a common size for many V8 engines. It features a chrome ring for durability and is built to ensure a solid seal against the cylinder wall.

Mahle is a well-known name in engine components, and this oil ring assembly is made to fit right into your piston. The 2.0mm oil ring and 0.113-inch expander work together to scrape excess oil from the cylinder walls, preventing it from getting into the combustion chamber. This helps maintain consistent oil levels and reduces smoke.

Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to your vehicle's service manual for specific installation procedures and torque specifications.
