Mahle Rings 4.3250in X 1/16in Edge Width THG Second Ring Plain Ring Set

Mahle is known for making well-built engine components, and these second ring sets are no exception. This specific set is designed for a 4.3250-inch bore and features a 1/16-inch edge width, making it a plain ring type for the second groove on your piston. These rings are crucial for proper engine sealing and performance, helping to control oil consumption and maintain compression.

The construction of these rings is straightforward and reliable, focusing on the essential function of sealing the combustion chamber. They are built to work effectively within the piston groove, ensuring a good seal against the cylinder wall. While they are a plain ring design, their accuracy in sizing and construction is key to their performance in the engine.

It's important to note that these rings are not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific service manual for installation procedures and recommended ring gap settings.
