Direct Replacement Rubber Tracks for the CAT 303 CR
Direct replacement rubber tracks for the CAT 303 CR are built for heavy-duty mini excavator applications where traction, stability, and uptime matter. These tracks are designed for dependable grip, smooth travel, and consistent performance across dirt, clay, gravel, demolition debris, utility work, grading, land clearing, excavation, and mixed jobsite terrain.
Heavy-Duty Construction for Daily Work
Premium virgin rubber compounds help resist tearing, chunking, cracking, dry rot, and premature tread wear under demanding field conditions. Continuous steel cord reinforcement adds internal strength, helps reduce stretching, and supports stable track performance through repeated turning, travel, and loading.
OEM Fit Guarantee
Machine-specific sizing, steel link spacing, and guide lug geometry are built for proper undercarriage engagement on the CAT 303 CR. Precision-aligned fitment helps support smooth travel, stable tracking, reduced vibration, and reliable sprocket contact.
Built to Protect the Undercarriage System
A well-built rubber track helps improve machine control while limiting unnecessary stress on rollers, idlers, and sprockets. For contractors running CAT equipment, that means better ride quality, stronger traction, less downtime, and better value over the life of the track.
Frequently Asked Questions
What size rubber track does the CAT 303 CR use?
The CAT 303 CR uses a 300x52.5Wx84 rubber track. Note the W (wide guide) guide-lug type — other guide types won't seat correctly on the rollers. Always confirm against your current track or the machine's spec plate, since some units shipped with more than one option.
Will this track fit my CAT 303 CR?
Yes — this track is matched to the CAT 303 CR by size and tread pattern. If your machine has a serial break or factory option, send the serial number and we'll verify fitment before shipping.
Do CAT 303 CR tracks sell in pairs?
Tracks are priced individually; a full machine needs two. Most owners replace both at once so wear stays even.
Are these OEM or aftermarket CAT 303 CR tracks?
OEM-grade aftermarket tracks built to factory fitment for the CAT 303 CR — same dimensions and guide type, continuous steel-cord belt, at a better price than dealer OEM.
Directional or block tread — which should I run?
For mixed dirt and gravel, most CAT 303 CR owners run a directional (multi-bar) tread for traction and mud release. Block tread wears better on hard surfaces and pavement.
