About this part

Product Details

In this set, you get the Mahle MS 4.050in 3.0MM Oil Ring Expanders with Standard Tension. These expanders are a key part of your piston ring assembly, working with the oil control ring to ensure it seals correctly against the cylinder wall. Proper oil ring function is crucial for preventing oil from entering the combustion chamber, which helps keep your engine running clean and efficiently.

Mahle is a well-known name in engine components, and these expanders are built to do their job. They are designed to fit a 4.050-inch bore with a 3.0mm oil ring width, and the standard tension is suitable for many rebuilds. When you're putting an engine back together, getting the piston rings seated and tensioned correctly makes a big difference in performance and longevity.
