The 450x81.5x76 Heavy Duty rubber track (18-inch) supports a broad verified fitment range across mini excavators. Key applications include Case CX80, Case CX80C, Hitachi ZX80, JCB 8080, JCB 8080TS, and JCB 8080ZTS, with 27 additional verified fits in the TrackTECH graph.
Maximize Uptime. Lower the Cost Per Hour. A failed track costs more than the replacement—it costs production time. This Heavy Duty replacement track is built for contractors and fleets that need dependable machine availability, predictable wear and useful traction instead of mid-job interruptions.
TrackTECH Advantage:
- Continuous Steel Cord: Jointless internal steel cable construction removes splice points and reinforces the track against stretching and high-load stress.
- Forged Steel Links: Heat-treated internal guide links support consistent sprocket engagement under repeated torque and load cycles.
- Wear & Ground Contact: Heavy-duty lug geometry balances traction, footprint stability and long-wearing contact across everyday jobsites.
- Controlled Travel: Tread geometry is selected for predictable forward and reverse movement during digging, trenching and repositioning.
