Piston Ring Set 4.055 Moly 3.0 2.0 3.0mm

The MAHLE ORIGINAL Piston Ring Set 4.055 Moly 3.0 2.0 3.0mm is a precision-engineered ring set designed for high-performance and rebuilt engine applications where durability and consistent compression are essential. This set is ideal for mechanics and enthusiasts working on stock engines, classic vehicle restorations, or modified powerplants.

Featuring a molybdenum (moly) facing on the top compression ring, this piston ring set reduces friction, extends ring life, and improves wear resistance. The configuration includes a 3.0mm top ring, a 2.0mm second compression ring, and a 3.0mm oil control ring, optimizing piston sealing while maintaining controlled oil film thickness on the cylinder wall. The 4.055-inch bore diameter specification indicates this set is engineered for various mid-sized displacement engines.

MAHLE ORIGINAL manufacture ensures these rings meet strict OEM tolerances and are tested for reliable performance in stock and moderately modified applications. Selecting the correct ring set is crucial for effective sealing of combustion pressure and controlling oil consumption over thousands of miles. This product is a valuable choice for anyone looking to enhance engine performance and longevity.
