Oil Rings (8pk) 4.030 3.0mm Standard Tension

The Oil Rings (8pk) 4.030 3.0mm Standard Tension set by MAHLE PISTONS is a crucial component for precision engine rebuilds and high-performance applications. These piston oil control rings are essential for managing oil consumption and lubrication within the combustion chamber, making them ideal for serious engine builds or restorations.

Designed to feature a 4.030-inch bore diameter and 3.0mm standard tension, these oil rings provide consistent radial pressure against cylinder walls for effective oil film control. The eight-ring pack configuration, consisting of four rings per piston for two pistons, ensures balanced ring dynamics and uniform wear patterns, which are critical for engine performance.

These oil rings are particularly beneficial for engine builders and technicians working on various domestic and import engines that require 4.030-inch bore specifications. Their standard tension design strikes a balance between durability and friction loss, making them suitable for street engines and mild performance builds where reliability is paramount.
