Will this track fit my IHI IS45NX?

Yes — this track is matched to the IHI IS45NX by size and tread pattern.

Directional or block tread — which should I run?

For mixed dirt and gravel, most IHI IS45NX owners run a directional (multi-bar) tread for traction and mud release. Block tread wears better on hard surfaces and pavement.

Do IHI IS45NX tracks sell in pairs?

Tracks are priced individually; a full machine needs two. Most owners replace both at once so wear stays even.
