Product Details
If you're rebuilding an engine, getting the right piston rings is a critical step for proper sealing and performance. This set from Mahle includes standard tension, drop-in rings designed to fit your pistons and restore compression. The ring sizes are 1/16 inch for the top and second rings, and 3/16 inch for the oil control ring, which is a common configuration for many engines.
Mahle is a well-known name in engine components, and these rings are made to meet the demands of a rebuild. They are designed to drop right into the piston grooves without needing special tools or modifications, making the installation process smoother. Proper ring seal is essential for preventing blow-by and ensuring your engine runs efficiently and powerfully.
Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific service manual for detailed installation instructions and specifications.
