The Hitachi EX18-2 is cataloged in more than one track width — 300 / 320 mm. Pick the width your undercarriage is actually set up for, then choose tread for the ground you work. Free freight to the lower 48 on every track, 24-month warranty.
Which width fits your Hitachi EX18-2
- 320x54x72 — 320 mm (13") wide, 54 mm pitch, 72 links
- 300x52.5x74 — 300 mm (12") wide, 52.5 mm pitch, 74 links
These are not interchangeable by preference — the width your machine takes is set by the roller frame and sprocket it left the factory with. Wider tread floats better on soft ground and spreads ground pressure; narrower runs cheaper, turns easier and clears tight spots. Measure the existing track across the tread face before you order.
Tread choice for the Hitachi EX18-2
Size gets the track on the machine; tread decides how it works and how long it lasts. What we stock for this one:

How these wear
Excavator undercarriages load one side hard on slew and travel, so link cracking usually shows up before the tread wears out. Replace in pairs where you can: a new track running against a stretched one loads the drive unevenly and you will feel it in the steering.
Same track, other machines
Track size follows undercarriage geometry, not brand, so one of these sizes shows up on machines from several makers. If you run any of these alongside the Hitachi EX18-2, it is the same belt:
- Bobcat 325
- Bobcat 325D
- Bobcat 325G
- Bobcat 328
- Bobcat 328E
- Bobcat X225
- Bobcat X325
- Bobcat X325D
- Bobcat X325G
- Bobcat X328
Not sure which you are running? Read the size off the inside of the old track, or call (850) 816-7898 and we will pull it off the machine record. The Track Finder works by make and model too.
