Tracks That Cross Over

The 400x72.5Wx72 track size is shared across these models — same track, verified cross-fit:

Built to Outlast OEM

  • Endless high-tensile cables — single-cure construction with no weak splice point.
  • 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.
  • Drop-forged steel links for strength where the track meets the drive system.

Direct Replacement Rubber Tracks for the Hitachi ZX50U

Direct replacement rubber tracks for the Hitachi ZX50U 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 Hitachi ZX50U. 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 Hitachi equipment, that means better ride quality, stronger traction, less downtime, and better value over the life of the track.

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.
How do I confirm the right track size for my Hitachi ZX50U?
Read the size stamped on the inside of your current track, or measure width x pitch x links. Not sure? Message us and we'll match it.
