These Mahle OE top compression rings are made with a cast claimer design, measuring 3.7760 inches in bore size and 5/64 inches in width. This specific design helps to ensure a proper seal between the piston and cylinder wall, which is crucial for maintaining engine compression and performance.

As a top compression ring, its primary job is to seal the combustion chamber, preventing combustion gases from escaping into the crankcase. The cast claimer construction is a well-known method for creating a durable and effective sealing surface that can withstand the high temperatures and pressures found in the combustion chamber. Mahle is a well-known name in engine components, and these rings are built to meet the demands of engine rebuilding.
