Frequently Asked Questions

Common fitment, shipping, and rubber track replacement questions

What size rubber track does the Case CX50B use?
The Case CX50B uses a 400x72.5Nx74 rubber track. Note the N (narrow 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 Case CX50B?
Yes — this track is matched to the Case CX50B 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 Case CX50B 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.
Are these OEM or aftermarket Case CX50B tracks?
OEM-grade aftermarket tracks built to factory fitment for the Case CX50B — 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 Case CX50B owners run a directional (multi-bar) tread for traction and mud release. Block tread wears better on hard surfaces and pavement.
