Frequently Asked Questions

Common fitment, shipping, and rubber track replacement questions

What size rubber track does the Cat 304CR use?
The Cat 304CR uses a 400x72.5Wx72 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 304CR?
Yes — this track is matched to the Cat 304CR 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 304CR tracks sell in pairs?
Tracks are priced individually; a full machine needs two. Most owners replace both at once so wear stays even.
What warranty comes with Cat 304CR 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.
Directional or block tread — which should I run?
For mixed dirt and gravel, most Cat 304CR owners run a directional (multi-bar) tread for traction and mud release. Block tread wears better on hard surfaces and pavement.
