Product Details
Mahle is well-known for making solid engine components, and this set of file fit piston rings is no exception. These rings are designed for a 4.375 inch bore and are +.005 inches oversize, meaning they're intended for engines that have been bored out slightly during a rebuild. The set includes three different ring sizes: two at 1/16 inch and one at 3/16 inch, which are standard tension sizes for many performance and heavy-duty applications.
File fit rings give you the flexibility to precisely set the ring gap yourself, which is crucial for optimal sealing and performance, especially in engines that see hard use or have been modified. This allows you to tailor the gap to your specific engine build and operating conditions. Keep in mind that these rings are not CARB approved and cannot be shipped to California.
