One track size, broad machine coverage. The 381x100.5x42 Heavy Duty Multi-Bar rubber track (15-inch) fits verified applications including ASV PT-50, ASV PT-60, ASV RC-50, ASV RC-60, ASV RT-60, and ASV RT-50 plus 16 additional verified machines. This 42-link configuration serves compact track loaders (CTLs), multi-terrain loaders, and specialty tracked equipment 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.
- Ride & Surface Control: Increased ground contact helps smooth travel and stabilize the machine across firm and mixed surfaces.
- Reinforced Rubber Construction: 100% virgin rubber and reinforced sidewalls help resist chunking, tearing, cuts and lateral jobsite impacts.
Smooth Ride & Surface Control Closely spaced bars spread ground contact for smoother travel, steadier surface control and reduced disturbance on turf, asphalt, pavement and finished surfaces. Best suited for turf, asphalt, landscaping, paved snow removal and finished surfaces. For operators comparing 381x100.5x42 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.
