Features and Benefits

Over 100 years of Undercarriage innovation:

Undercarriage components play a vital role in the efficient operation and movement of your equipment’s undercarriage system. Selecting high-quality undercarriage parts for heavy equipment is crucial in maintaining a sturdy and reliable support structure for your machines. Cat® undercarriage parts work as a powerful system to propel your machine over all types of terrain. Most importantly, we know how to help you get the most from your undercarriage investment. When you consider that 50% of a track-type machine's ownership and operating costs come from its undercarriage, it makes sense to invest in a system that will deliver the most value to your bottom line.

Cat Undercarriage Features & Benefits:

We offer more undercarriage options for your Cat machines than any other manufacturer because we know that the more precisely you match iron to application, the more effective and efficient your work will be.

Whether you’re looking for the lowest upfront cost, longer wear life or lower operating costs per hour, we have the right undercarriage solution for your business.

Every Cat Undercarriage is designed by Caterpillar engineers and built to exact specifications based on the real-world experience of our customers. And our Undercarriage systems come with industry leading warranties, so when you choose a Cat Undercarriage you know it’s the right choice.
