Frequently Asked Questions

Common fitment, shipping, and rubber track replacement questions

Will this track fit my Kobelco SK70SR?
Yes — this track is matched to the Kobelco SK70SR by size and tread pattern.
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.
