The TrackTECH Advantage

  • 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.

Direct Replacement Rubber Tracks for the Komatsu PC30MR-3

Direct replacement rubber tracks for the Komatsu PC30MR-3 are built for heavy-duty compact equipment applications where traction, stability, and uptime matter. These tracks are designed for dependable grip, smooth travel, and consistent performance across dirt, clay, gravel, demolition debris, utility work, grading, land clearing, excavation, and mixed jobsite terrain.

Heavy-Duty Construction for Daily Work

Premium virgin rubber compounds help resist tearing, chunking, cracking, dry rot, and premature tread wear under demanding field conditions. Continuous steel cord reinforcement adds internal strength, helps reduce stretching, and supports stable track performance through repeated turning, travel, and loading.

OEM Fit Guarantee

Machine-specific sizing, steel link spacing, and guide lug geometry are built for proper undercarriage engagement on the Komatsu PC30MR-3. Precision-aligned fitment helps support smooth travel, stable tracking, reduced vibration, and reliable sprocket contact.

Built to Protect the Undercarriage System

A well-built rubber track helps improve machine control while limiting unnecessary stress on rollers, idlers, and sprockets. For contractors running Komatsu equipment, that means better ride quality, stronger traction, less downtime, and better value over the life of the track.

Frequently Asked Questions About Komatsu PC30MR-3

Questions & Answers

What size rubber track does the Komatsu PC30MR-3 use?
The Komatsu PC30MR-3 uses a 300x52.5Kx86 rubber track. Note the K guide-lug type — other guide types won't seat correctly on the rollers, and guide letters are not standardized between manufacturers. 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 Komatsu PC30MR-3?
Yes — this track is matched to the Komatsu PC30MR-3 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.
Do you stock undercarriage parts for the Komatsu PC30MR-3?
Yes — along with the rubber track we carry bottom rollers, drive sprockets, top rollers for the Komatsu PC30MR-3, so you can refresh the whole undercarriage in one order.
How long do Komatsu PC30MR-3 rubber tracks last?
Most rubber tracks last 1,200–1,600 operating hours depending on terrain, alignment, and tension. Keeping tracks tensioned and clearing debris daily extends life.
Directional or block tread — which should I run?
For mixed dirt and gravel, most Komatsu PC30MR-3 owners run a directional (multi-bar) tread for traction and mud release. Block tread wears better on hard surfaces and pavement.
