For one century, Caterpillar’s research in undercarriages has yielded as a result a better machine, higher productivity, and a well represented value in its undercarriage. Quality is the critical link between you and the maximum value of your track CAT machine. No company has invested more Money than Caterpillar to provide a consistently high quality undercarriage system. Independent lab tests have proven that CAT components for undercarriage systems exceed all others due to constant steel quality, the hardness of the surface, the depth of hardening and other important factors. As a result, no other manufacturer can offer such a long useful life, ease of service and the value that Cat undercarriages offer.
