Mahle MS 4.040in+ .005in 1.5 1.5 3.0 mm File Fit Rings

When you're rebuilding an engine and need to ensure a solid seal between the piston and cylinder wall, a good set of piston rings is essential. These Mahle MS file-fit rings are designed for that purpose. They come in a 1.5mm, 1.5mm, 3.0mm configuration, which is a common setup for many performance and rebuild applications. The file-fit design means you'll need to gap them yourself to perfectly match your cylinder bore, giving you that extra bit of control for a custom fit.

Mahle is a well-known name in engine components, and these rings are built to perform. The +.005 inch sizing indicates they are intended for a cylinder bore that has been honed out by 0.005 inches, typical after an engine has been bored over. This attention to detail in sizing and the file-fit nature of the rings means you're getting a part that allows for a precise installation, crucial for optimal compression and oil control. Remember, these are not CARB approved and cannot be shipped to California.
