Will this track fit my Doosan DX55-R7?

Yes — this track is matched to the Doosan DX55-R7 by size and tread pattern.

Do Doosan DX55-R7 tracks sell in pairs?

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

Directional or block tread — which should I run?

For mixed dirt and gravel, most Doosan DX55-R7 owners run a directional (multi-bar) tread for traction and mud release. Block tread wears better on hard surfaces and pavement.
