For contractors running IHI equipment, that means better ride quality, stronger traction, less downtime, and better value over the life of the track.\u003c\/p\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eWhat size rubber track does the IHI IS50UX use?\u003c\/h3\u003e\u003cp\u003eThe IHI IS50UX uses a 400x72.5Wx74 rubber track. Note the W (wide guide) guide-lug type — other guide types won't seat correctly on the rollers. Always confirm against your current track or the machine's spec plate, since some units shipped with more than one option.\u003c\/p\u003e\u003ch3\u003eWill this track fit my IHI IS50UX?\u003c\/h3\u003e\u003cp\u003eYes — this track is matched to the IHI IS50UX by size and tread pattern. If your machine has a serial break or factory option, send the serial number and we'll verify fitment before shipping.\u003c\/p\u003e\u003ch3\u003eDo you stock undercarriage parts for the IHI IS50UX?\u003c\/h3\u003e\u003cp\u003eYes — along with the rubber track we carry top rollers for the IHI IS50UX, so you can refresh the whole undercarriage in one order.\u003c\/p\u003e\u003ch3\u003eDirectional or block tread — which should I run?\u003c\/h3\u003e\u003cp\u003eFor mixed dirt and gravel, most IHI IS50UX owners run a directional (multi-bar) tread for traction and mud release. Block tread wears better on hard surfaces and pavement.\u003c\/p\u003e\u003ch3\u003eHow do I confirm the right track size for my IHI IS50UX?\u003c\/h3\u003e\u003cp\u003eRead the size stamped on the inside of your current track, or measure width x pitch x links.
