Product Details
These Mahle drop-in piston rings measure 4.055 inches in bore size, with a 1.0mm top ring, 1.0mm second ring, and a 2.0mm oil ring. This specific sizing and tension is designed to work as a direct replacement in many popular engine builds, simplifying the rebuilding process. Mahle is a well-known name in engine components, and this set is built to meet the demands of a refreshed engine.
The construction of these rings is focused on providing a good seal between the piston and cylinder wall. This is crucial for maintaining compression, controlling oil consumption, and ensuring efficient combustion. The standard tension design means they are intended to work with stock pistons and cylinders without requiring special installation tools or modifications, making them a practical choice for many engine overhauls. Remember that these rings are not CARB approved and cannot be shipped to California.
