The 320x86x53 Heavy Duty C-Block rubber track (13-inch) is a direct replacement for verified applications including Bobcat T76, CAT 259, CAT 259B, CAT 259B3, CAT 259D, and CAT 259D3. This 53-link configuration is built for compact track loaders (CTLs) working across demanding mixed-terrain jobsites.
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.
- Reinforced Rubber Construction: 100% virgin rubber and reinforced sidewalls help resist chunking, tearing, cuts and lateral jobsite impacts.
Everyday Heavy-Duty Value Dependable traction, stable handling and long wear across dirt, gravel, clay, hard pack and mixed construction sites. Best suited for general dirt, gravel, clay, hard-packed ground and mixed-use construction. For operators comparing 320x86x53 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.
