Description
Precision piston rings are foundational to engine performance, and MAHLE’s file-fit design gives you the control to dial in exact clearances for your specific build. Low-tension plasma moly rings reduce friction losses while maintaining reliable sealing, translating to better ring life and more power reaching the wheels. If you’re building or rebuilding a 4.040-inch bore engine and demand proven motorsports-grade components, this 8-cylinder set delivers the durability and performance characteristics that serious racers and builders expect.
