    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 CAT 306 use?
    The CAT 306 takes 400x72.5Wx76 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 CAT 306?
    For the CAT 306 we carry Block, a good fit for mixed dirt, gravel and hardpack. Call (850) 816-7898 if you want to talk through your jobsite.
    How much do CAT 306 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 CAT 306?
    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 CAT 306?
    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 CAT 306?
    We stock tracks for the CAT 306 today. Need a sprocket, idler or roller? Call (850) 816-7898 and we'll find the right one for you.
