Frequently Asked Questions

Common fitment, shipping, and rubber track replacement questions

Will this track fit my CAT 239D3?
Yes — this track is matched to the CAT 239D3 by size and tread pattern.
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.
