Product Details
This is a Mahle MS 4.155 inch piston ring set, designed as a standard tension, drop-in replacement. The ring sizes are 1.5mm for the top and second rings, and 3.0mm for the oil ring. These rings are intended to fit a variety of engines where this specific bore size and ring configuration is required.
Mahle is a well-known name in engine components, and this set is built to meet the needs of engine rebuilds. The standard tension design ensures a solid seal against the cylinder wall, which is crucial for proper compression and oil control. Being a drop-in style means they are designed to install directly into the piston grooves without requiring special tools or modifications, making them a practical choice for many engine builds.
It's important to note that this ring set is not CARB approved and cannot be shipped to California. Always refer to your specific engine's service manual for correct installation procedures and specifications.
