Mahle Rings Chevy Race 427/454 Engs Chry Race 383/426 Engs Moly Ring Set

These Mahle Moly piston rings are built with a 1.5mm top ring, 2.0mm second ring, and 4.0mm oil ring, a common configuration for performance builds. They are designed for specific race engines, including Chevy 427 and 454 cubic inch V8s, and Chrysler 383 and 426 cubic inch V8s. The moly coating on the top ring helps reduce friction and wear, which is crucial for engines that see hard use and high RPMs. This coating also aids in seating the rings quickly against the cylinder wall, ensuring a good seal right away.

Mahle is a well-known name in engine components, and this ring set is made to meet the demands of racing applications. The specific ring dimensions are chosen to work well with the piston designs typically found in these high-performance V8s. Proper ring seal is essential for making good power and keeping oil out of the combustion chamber, and this set is engineered to help achieve that.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine builder's recommendations or the specific service manual for your application to ensure proper installation and compatibility.
