Product Details
This Mahle piston ring set includes standard tension, drop-in rings with a 1.5mm top ring, 1.5mm second ring, and a 3.0mm oil ring. These rings are designed to fit a 4.125 inch bore size. They are a well-built option for engine rebuilds where a direct fit is needed without modification.
Mahle is a well-known name in engine components, and this set is made to meet the demands of a rebuild. The standard tension design ensures a good seal against the cylinder wall, helping to maintain compression and prevent blow-by. The three-piece oil ring design is effective at controlling oil consumption.
Please note that these rings are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
