The TrackTECH Difference

  • Drop-forged steel links for strength where the track meets the drive system.
  • Continuous steel cord — up to 40% stronger than typical aftermarket tracks, resisting stretch and de-tracking.
  • Premium virgin rubber — anti-chunk compound built for long service life in abrasive conditions.
  • Precision OEM alignment — a reinforced roller path keeps running smooth and vibration low.

Frequently Asked Questions

Common fitment, shipping, and rubber track replacement questions

Will this track fit my Komatsu PC20MR?
Yes — this track is matched to the Komatsu PC20MR by size and tread pattern.
Do Komatsu PC20MR 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.
