Tracks That Cross Over

These machines run the same 450x81.5x76 track, so this fitment crosses over:

The TrackTECH Difference

Endless high-tensile cables — single-cure construction with no weak splice point.
Precision OEM alignment — a reinforced roller path keeps running smooth and vibration low.
Continuous steel cord — up to 40% stronger than typical aftermarket tracks, resisting stretch and de-tracking.
Drop-forged steel links for strength where the track meets the drive system.

Will this track fit my Kobelco SK75-SR3E?

Yes — this track is matched to the Kobelco SK75-SR3E by size and tread pattern.

Do Kobelco SK75-SR3E tracks sell in pairs?

Tracks are priced individually; a full machine needs two. Most owners replace both at once so wear stays even.

Directional or block tread — which should I run?

For mixed dirt and gravel, most Kobelco SK75-SR3E owners run a directional (multi-bar) tread for traction and mud release. Block tread wears better on hard surfaces and pavement.
