What does 'standard tension' mean for these piston rings?

Standard tension rings provide a consistent and predictable amount of pressure against the cylinder wall. This ensures a good seal for compression and oil control in many common engine applications.

Are these rings suitable for all engine rebuilds?

These rings are designed for a 4.125-inch bore and standard tension applications. It's important to verify that these specifications match your specific engine's requirements and the intended build.

Why can't these rings be shipped to California?

This part is not CARB approved, which means it does not meet California Air Resources Board emissions standards. Therefore, it cannot be legally shipped to California.

Product Details

These Mahle OE piston rings are built with a standard tension design, meaning they offer a predictable and reliable seal against the cylinder wall. The 4.125-inch bore size is a common specification for many larger displacement engines, and Mahle has a long history of providing well-built internal engine components.

The PC479 set uses plain ring technology, focusing on effective sealing without complex coatings. This straightforward approach is often preferred for rebuilds where durability and consistent performance are key. Mahle's OE designation means these rings are made to meet or exceed the original equipment specifications for the engines they are designed for, ensuring a proper fit and function when you're putting your engine back together.

When rebuilding an engine, the piston rings are a critical component for proper compression and oil control. This set is designed for standard tension applications, so be sure it matches the requirements for your specific engine build.
