The TrackTECH Difference

  • 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.
  • Premium virgin rubber — anti-chunk compound built for long service life in abrasive conditions.
  • Drop-forged steel links for strength where the track meets the drive system.

  • 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.
