Frequently Asked Questions

Common fitment, shipping, and rubber track replacement questions

What size rubber track does the Cat 305.5 use?
The Cat 305.5 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 305.5?
Yes — this track is matched to the Cat 305.5 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.
What warranty comes with Cat 305.5 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.
How long do Cat 305.5 rubber tracks last?
Most rubber tracks last 1,200–1,600 operating hours depending on terrain, alignment, and tension. Keeping tracks tensioned and clearing debris daily extends life.
Directional or block tread — which should I run?
For mixed dirt and gravel, most Cat 305.5 owners run a directional (multi-bar) tread for traction and mud release. Block tread wears better on hard surfaces and pavement.
