Cast Iron

When Cost Efficiency Is Paramount

Grover specializes in producing cast iron piston rings and G2 Durabar rings. We offer various chemistries to meet a wide range of temperature, speed and size requirements.


  • Lower cost
  • Grover’s specially-formulated 200 series of iron meets SAE-J1236 specifications.


  • Low Friction
  • Wear resistant
  • Produces consistent pressure against the bore


  • GC-211 Cast Iron: Specially designed for piston rings in reciprocating or rotary applications. The microstructure and chemistry of GC-211 cast iron offers the ideal material for wear and lubricity in a wide range of bore materials.
  • GC-225 Cast Iron: Designed for high volume rotary applications. GC-225 cast iron offers a homogenous matrix and chemistry, providing excellent wear characteristics.
  • GC-607 Cast Iron: Specially designed for large diameter reciprocating engine rings where the ring will experience higher temperature and impacts.
