The Caterpillar 104-9277 Ripper Shank Assembly is a genuine OEM-specification ground engaging tool designed for the Caterpillar D11N and D11R dozers. This ripper shank is a critical component that connects to the ripper frame and holds the ripper tooth point, providing the structural backbone for ripping operations in hard materials, rock, and compacted ground.
Manufactured from 35CrMo (Chromium-Molybdenum alloy steel), this ripper shank offers superior strength, toughness, and wear resistance. The 35CrMo material provides excellent hardenability and resistance to impact and fatigue, making it ideal for the extreme forces encountered during ripping operations.
The D11N and D11R are large dozers used in mining, heavy construction, quarrying, and land clearing applications.
