Verified Caterpillar Application
This track configuration is verified for the Caterpillar 303 compact excavator. Caterpillar model families may use different tracks across serial-number ranges, so the model name alone should not be used as the final fitment check.
Confirm Fitment Before Ordering
Verify the 300 mm width, 52.5 mm pitch and 84-link count marked on the current track. Provide the exact Caterpillar model and serial number. If the markings are worn, send photos through our Part Finder Request. Browse the rubber tracks hub or shop excavator rubber tracks.
