Product Details
Mahle is a well-known name in engine components, and this piston ring set is a solid option for many engine rebuilds. These rings are designed to drop right into your pistons, simplifying the installation process. They feature a specific ring configuration: the top ring has a 1.2mm width, the second ring is also 1.2mm, and the oil ring is 2.8mm. This precise sizing is crucial for proper sealing between the piston and cylinder wall, which helps maintain compression and control oil consumption.
When you're rebuilding an engine, getting the piston rings right is key to its performance and longevity. These Mahle rings are made to meet the demands of an engine rebuild, ensuring a good seal for optimal power and efficiency. Because they are a universal fit, they can be used across a wide range of applications where these specific dimensions are required.
Please note that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine's specific service manual for installation procedures and specifications.
