Frequently Asked Questions
What size rubber track does the Kobelco SK70SR use?
The Kobelco SK70SR uses a 450x81.5x76 rubber track. Always confirm against your current track or the machine's spec plate, since some units shipped with more than one option.
Will this track fit my Kobelco SK70SR?
Yes — this track is matched to the Kobelco SK70SR 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.
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.
Directional or block tread — which should I run?
For mixed dirt and gravel, most Kobelco SK70SR owners run a directional (multi-bar) tread for traction and mud release. Block tread wears better on hard surfaces and pavement.
Do you stock undercarriage parts for the Kobelco SK70SR?
Yes — along with the rubber track we carry top rollers for the Kobelco SK70SR, so you can refresh the whole undercarriage in one order.
