4.445IN BORE DIA. 1/16IN EDGE WIDTH GREY IRON THG SECOND RING. RING SET PLAIN

The Clevite 302-0316 is a set of performance piston rings engineered for optimal sealing and maximum power output in demanding, high-performance racing engines.

These rings are constructed from SAE 9254 high alloy steel, offering superior fatigue resistance and durability. They feature a High Velocity Oxygen Fueled Thermal Spray Coating (HV385) which enhances ring face wear by over 50% without increasing cylinder bore wear, providing a balance of strength and scuff resistance. The HV385 coating, combined with a micro-polished face, demonstrates the lowest coefficient of friction in both low-speed/high-load and high-speed/low-load operating conditions.
