Description

The Mahle 3020257B is a piston ring set designed for high-performance racing engines. These rings are constructed from SAE 9254 high alloy steel, offering superior fatigue resistance and durability.

The set features a 5/64" edge width and is designed for a 4.250" bore diameter. The piston ring technology includes a High Velocity Oxygen Fueled Thermal Spray Coating (HV385) which improves ring face wear by over 50% without increasing bore wear.
