    ENGINEERED FOR THE JOBSITE

    Built Tough

    Heavy-duty replacement rubber tracks engineered for compact track loaders, tracked skid steers, mini excavators, mini track loaders, and demanding construction equipment applications.

    • 100% Virgin Rubber

      Engineered to resist chunking, tearing, and cutting in harsh, abrasive environments.

    • Continuous Steel Cords

      Jointless internal cable architecture eliminates structural weak points and maximizes overall tensile strength.

    • Drop-Forged Links

      Precision heat-treated guide lugs ensure exact sprocket engagement and prevent de-tracking under heavy side-loads.

    • Corrosion Resistant

      The internal steel framework is fully encapsulated to prevent oxidation, rust, and moisture penetration.

    • Reinforced Sidewalls

      Extra-thick vulcanized rubber and tapered edge profiles protect against curb slashing and lateral impacts from jobsite debris.

    • Low-Vibration Tread

      Optimized lug spacing and pitch geometry absorb shock, reducing undercarriage wear and minimizing cabin vibration.

    Frequently Asked Questions

    Fitment, availability, fulfillment, and support for this product

    What size tracks does the Komatsu PC30MR-5 use?
    The Komatsu PC30MR-5 takes 300x52.5Nx86 rubber tracks. That's width x pitch x number of links, in millimeters. Check the size molded on the inside of your old track, or call us at (850) 816-7898 and we'll confirm it for you.
    Which tread is best for the Komatsu PC30MR-5?
    For the Komatsu PC30MR-5 we carry Directional, a good fit for mud, snow and loose ground where you need bite. Call (850) 816-7898 if you want to talk through your jobsite.
    How much do Komatsu PC30MR-5 tracks cost?
    Prices are per track and change with the size and tread you pick, so check the price next to your option above. Most owners replace both tracks at once so they wear evenly. Shipping is always free to the lower 48.
    How fast can I get tracks for my Komatsu PC30MR-5?
    In-stock tracks ship free from U.S. warehouses and usually arrive in 1 to 3 business days. Every TrackTECH rubber track comes with a 24-month warranty and 90-day returns.
    Should I replace the tracks on my Komatsu PC30MR-5?
    If the tracks are cracked, missing lugs, showing steel cord or slipping on the sprocket, it's time. While you're at it, check the sprockets, rollers and idlers, because worn steel parts will wear out new tracks fast.
    Do you sell undercarriage parts for the Komatsu PC30MR-5?
    We stock tracks for the Komatsu PC30MR-5 today. Need a sprocket, idler or roller? Call (850) 816-7898 and we'll find the right one for you.
