About this part

Product Details

This Mahle MS piston ring set includes all the rings you need for one piston, and you get a full set for your engine. The rings are designed for a 4.255 inch bore and are file-fit, meaning you'll adjust the end gap yourself during installation to achieve a precise fit. This set features a 1.0mm top ring, a 1.0mm second ring, and a 2.0mm oil control ring, all with standard tension.

Mahle is a well-known name in engine components, and this set is built to perform. The file-fit design is common in performance and rebuild applications where achieving the exact ring-to-wall clearance is critical for proper sealing and engine health. This approach allows for a custom fit that can improve compression and oil control, especially in engines that have been bored or honed beyond standard sizes. Remember, these rings are not CARB approved and cannot be shipped to California.
