Will this track fit my IHI IS45UJ?

Yes — this track is matched to the IHI IS45UJ by size and tread pattern.

How long do IHI IS45UJ 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.

Are these OEM or aftermarket IHI IS45UJ tracks?

OEM-grade aftermarket tracks built to factory fitment for the IHI IS45UJ — 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 IHI IS45UJ owners run a directional (multi-bar) tread for traction and mud release. Block tread wears better on hard surfaces and pavement.
