Direct Replacement Rubber Tracks for the Case CX31B

Direct replacement rubber tracks for the Case CX31B are built for heavy-duty compact equipment 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 Case CX31B. 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 Case equipment, that means better ride quality, stronger traction, less downtime, and better value over the life of the track.

Frequently Asked Questions About Case CX31B

Questions & Answers

What size rubber track does the Case CX31B use?
The Case CX31B uses a 300x52.5Kx88 rubber track. Note the K guide-lug type — other guide types won't seat correctly on the rollers, and guide letters are not standardized between manufacturers. 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 CX31B?
Yes — this track is matched to the Case CX31B 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 Case CX31B 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 Case CX31B 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 fast will my track ship?
In-stock tracks ship fast from US warehouses, most within 1–2 business days, with tracking sent as soon as it leaves the dock.
