Mahle Rings CP20 Std Tension 3.0MM Oil Rings 4.040in Bore Chrome Ring Set

When you're rebuilding the top end of your engine, getting the right piston rings is crucial for proper sealing and performance. This Mahle OE chrome ring set is designed for a 4.040-inch bore, a common size for many V8 engines. The 3.0MM oil rings are built for standard tension, which is a reliable choice for a wide range of applications.

Mahle is a well-known name in engine components, and these rings are made to fit right. The chrome plating on the top ring helps with durability and wear resistance, especially important in high-heat environments. Getting the ring gap set correctly during installation is key to ensuring these rings perform as they should, helping to keep oil out of the combustion chamber and maintain good compression.
