Frequently Asked Questions
What size rubber track does the CAT 239D3 use?
The CAT 239D3 uses a 320x86x49 rubber track. 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 239D3?
Yes — this track is matched to the CAT 239D3 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.
Directional or block tread — which should I run?
For mixed dirt and gravel, most CAT 239D3 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 239D3 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 CAT 239D3 tracks?
OEM-grade aftermarket tracks built to factory fitment for the CAT 239D3 — same dimensions and guide type, continuous steel-cord belt, at a better price than dealer OEM.
