Frequently Asked Questions

Common fitment, shipping, and rubber track replacement questions

Will this track fit my Kubota U45S?
Yes — this track is matched to the Kubota U45S by size and tread pattern.
Do Kubota U45S tracks sell in pairs?
Tracks are priced individually; a full machine needs two. Most owners replace both at once so wear stays even.
How fast will my track ship?
In-stock tracks ship fast from US warehouses, most within 1–2 business days, with tracking sent as soon as it leaves the dock.
Are these OEM or aftermarket Kubota U45S tracks?
OEM-grade aftermarket tracks built to factory fitment for the Kubota U45S — same dimensions and guide type, continuous steel-cord belt, at a better price than dealer OEM.
