- Premium virgin rubber — anti-chunk compound built for long service life in abrasive conditions.
- Drop-forged steel links for strength where the track meets the drive system.

Frequently Asked Questions
What size rubber track does the CAT 305E2CR use?
The CAT 305E2CR uses a 400x72.5Wx76 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 305E2CR?
Yes — this track is matched to the CAT 305E2CR 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 you stock undercarriage parts for the CAT 305E2CR?
Yes — along with the rubber track we carry bottom rollers, front idlers, top rollers for the CAT 305E2CR, so you can refresh the whole undercarriage in one order.
Directional or block tread — which should I run?
For mixed dirt and gravel, most CAT 305E2CR owners run a directional (multi-bar) tread for traction and mud release. Block tread wears better on hard surfaces and pavement.
What warranty comes with CAT 305E2CR tracks?
Our rubber tracks carry a 24-month warranty against manufacturing defects, with continuous steel cords and wear-resistant compounds. Technicians by trade; heavy duty comes standard.
