Mahle Rings Performance 3.997in x .0935 .184in RW Plasma Moly Top Ring Moly Ring Set

This Mahle piston ring set features a plasma moly top ring and a moly ring set, measuring 3.997 inches in bore size. The plasma moly coating on the top ring is known for its exceptional hardness and wear resistance, helping to maintain a tight seal against the cylinder wall even under demanding conditions. This construction is key to preventing blow-by and ensuring efficient combustion.

Designed for performance applications, these rings are built to withstand higher operating temperatures and pressures often found in modified engines. The moly coating further enhances the ring's ability to reduce friction and resist scuffing, contributing to longer engine life and consistent performance. Proper installation is crucial for these rings to function as intended, ensuring optimal compression and oil control.
