About Our Caterpillar Parts
We manufacture OEM-specification replacement rubber parts for Caterpillar heavy equipment, covering cab mounts and vibration isolation components used in CAT excavators, motor graders, dozers, and compactors. Our CAT parts are produced under ISO 9001:2015 quality management and dimensionally verified against Caterpillar engineering specifications.
The CAT 211-4987 cab mount is one of the most widely used cab isolation components for CAT 320-336 series excavators operating in US construction fleets. Our production matches original CAT hardness, geometry, and bonding system specifications. Certificates of conformance are available on request for fleet maintenance documentation programs.
Caterpillar equipment requires precise rubber compound hardness for correct cab isolation performance. We verify Shore A values against CAT target specifications, with tolerance control tighter than ±2 Shore A units.
