Product Details
These Mahle drop-in piston rings feature a 1/16 inch top ring, a 1/16 inch second ring, and a 3/16 inch oil ring. This combination is a common setup for many engines, designed to provide a good seal between the piston and cylinder wall. The standard tension design ensures they seat properly without excessive force, making them a straightforward replacement part for a rebuild or repair.
Mahle is a well-known name in engine components, and this ring set is built to meet the demands of everyday driving. The materials and manufacturing processes are focused on creating a durable seal that helps maintain compression and control oil consumption. When you're putting an engine back together, having reliable piston rings is crucial for its performance and longevity.
This set is considered a universal fit, meaning it's designed to work across a wide range of applications, but it's always a good idea to double-check the specific dimensions against your pistons. Please note that these rings are not CARB approved and cannot be shipped to California.
