The 320x86x49 Heavy Duty Staggered Block rubber track (13-inch) supports a broad verified fitment range across compact track loaders (CTLs). Key applications include Bobcat T180, Bobcat T190, Bobcat T550, Bobcat T590, Bobcat T595, and CAT 239D, with 6 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:
Dependable All-Around Performance Large-lug block tread delivers dependable all-around traction and durable performance across dirt, hard surfaces, mud, rip rap and changing construction conditions. Best suited for general construction, dirt, hard surfaces, mud, rip rap and mixed jobsites. For operators comparing 320x86x49 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
Heavy-duty replacement rubber tracks engineered for compact track loaders, tracked skid steers, mini excavators, mini track loaders, and demanding construction equipment applications.
Engineered to resist chunking, tearing, and cutting in harsh, abrasive environments.
Jointless internal cable architecture eliminates structural weak points and maximizes overall tensile strength.
Precision heat-treated guide lugs ensure exact sprocket engagement and prevent de-tracking under heavy side-loads.
The internal steel framework is fully encapsulated to prevent oxidation, rust, and moisture penetration.
Extra-thick vulcanized rubber and tapered edge profiles protect against curb slashing and lateral impacts from jobsite debris.
Optimized lug spacing and pitch geometry absorb shock, reducing undercarriage wear and minimizing cabin vibration.
Tread Pattern Guide
Compare common TrackTECH rubber track tread patterns by traction, ride comfort, surface protection, and jobsite conditions.
Balanced Jobsite Performance
Best for: general construction, dirt, gravel, clay, and mixed jobsite use.
C-Block tracks are a strong all-around option for compact track loaders working across everyday jobsite conditions. They provide dependable traction, a stable ride, and balanced wear life without being overly aggressive on the ground.
Aggressive Traction
Best for: mud, loose soil, slopes, clay, and soft ground.
Zig-Zag tracks use an alternating lug design to improve bite and help the track clean out in loose or wet conditions. This pattern is a strong choice when traction and hillside control matter more than surface protection.
Severe-Duty Terrain
Best for: forestry, mulching, extreme land clearing, and the most severe off-road environments.
Designed for high-horsepower CTLs in dense brush, jagged terrain, and debris-heavy conditions. The most aggressive TrackTECH tread for severe duty — built for durability, puncture resistance, and relentless traction when clearing heavy brush or earth.
Fortified Core Defense: ultra-reinforced center guide deflects stumps, jagged rocks, and sharp forestry debris from the core. Maximum Bite: deep aggressive lugs deliver uncompromising forward drive from deep clay to heavy snowpack.
Trade-off: overkill on sensitive turf or finished pavement — runs rough and will tear up the ground. Ideal surfaces: mulch/brush, deep clay, jagged rock, snow.
Mini Excavator Control
Best for: mini excavators, trenching, grading, utility work, and mixed surfaces.
Directional tracks are commonly used on mini excavators where forward traction, controlled movement, and dependable wear are important. This pattern helps provide predictable movement across dirt, gravel, clay, and general excavation conditions.
