Caterpillar Replacement Belts

This collection features premium aftermarket belts designed to replace original Caterpillar® (CAT®) part numbers used in construction, mining, and heavy equipment. These belts are built for high-load, high-heat environments—ensuring reliable power transmission in demanding applications.

Typical OEM part numbers include formats like 9X-xxxx, 5M-xxxx, or 1R-xxxx (e.g., 9X-5135, 5M-2894, 1R-1021). Each product listing clearly identifies the Caterpillar number and ships as a durable aftermarket cross reference matched for profile, tension, and longevity.

Ideal for loaders, excavators, dozers, generators, and diesel-powered systems, these belts help keep your CAT equipment running smoothly with reduced downtime and dependable performance in the field or on the job site.
