Why Choose a CGI Cylinder Head?

Heavy-duty Caterpillar engines produce substantial cylinder pressure and thermal load. Compacted Graphite Iron (CGI) is stronger than traditional gray cast iron while maintaining excellent thermal stability.

Benefits of CGI Construction

• Increased strength over conventional cast iron
• Improved resistance to cracking
• Better fatigue resistance
• Greater dimensional stability under heavy loads
• Excellent durability in high-horsepower applications
• Longer service life in demanding commercial environments

Premium Inconel Exhaust Valves

This cylinder head is equipped with high-temperature Inconel exhaust valves, providing additional durability in one of the hottest areas of the engine.

Inconel Valve Benefits

• Superior resistance to extreme exhaust temperatures
• Improved resistance to valve burning
• Increased durability under heavy towing and high-load operation
• Longer valve life

When combined with a CGI casting, Inconel valves create a durable cylinder head package.
