One track size, broad machine coverage. The 450x86x56 Heavy Duty Z-Max rubber track (18-inch) fits verified applications including CAT 279C2, CAT 279D, CAT 279D3, CAT 289C2, CAT 289D, and CAT 289D3 plus 42 additional verified machines. This 56-link configuration serves compact track loaders (CTLs) and mini excavators across demanding work environments.
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.
- Traction & Cleanout: More aggressive lug geometry adds biting edges and open space for loose material to clear from the tread.
- Controlled Travel: Tread geometry is selected for predictable forward and reverse movement during digging, trenching and repositioning.
Aggressive Off-Road Traction Aggressive Z-pattern provides strong forward bite and lateral hold on side slopes, trenching work, mud, clay and loose ground. Best suited for side slopes, trenching, mud, loose ground and severe off-road traction. For operators comparing 450x86x56 rubber tracks, the tread choice should match the ground conditions, machine application and the balance you want between traction, ride quality, cleanout and surface disturbance.
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.
