Heavy-duty 381x100.5x42 aftermarket replacement rubber tracks for the ASV PT-50, with a Multi-Bar tread built for dependable traction, stable travel, and controlled ground contact across dirt, mud, snow, turf, packed soil, and mixed jobsites. This application uses a supplier-verified steel-reinforced replacement belt rather than ASV's genuine polycord track construction.
ASV's Posi-Track undercarriage is designed around internal positive drive, multiple ground-contact points, suspension, and rubber-on-rubber wheel-to-track contact. Those features help the machine maintain traction, flotation, low ground pressure, ride quality, and stability, so replacement-track geometry and dependable drive-lug engagement matter as much as tread depth.
The Multi-Bar pattern creates repeated cross-ground traction edges for steady grip and frequent surface contact. It is a strong mixed-terrain choice for landscaping, grading, site preparation, utility work, snow, dirt, mud, and turf-adjacent applications where predictable steering and smoother travel matter.
ASV genuine Posi-Track belts are engineered without a steel core and use flexible embedded high-tensile polycord. The aftermarket track sold on this page is constructed differently: supplier-verified internal steel cables are distributed evenly through the belt to add strength and protect high-stress areas. It is a heavy-duty aftermarket alternative, not an ASV genuine track.
Evenly distributed internal steel-cable reinforcement supports belt strength while an advanced low-abrasion rubber compound improves resistance to cuts, tearing, edge damage, and premature wear. The construction is designed for repeated steering, travel, pushing, and load cycles in demanding compact-equipment use.
Inspect drive sprocket rollers, internal drive-lug contact surfaces, roller wheels, idlers, guide areas, debris buildup, alignment, and track tension before installation. Worn components, packed material, or incorrect tension can accelerate belt wear and reduce service life. Set final tension to the applicable service specification for the installed replacement track.
Nationwide fulfillment is available, backed by a 24-month warranty against manufacturing defects and application support when needed.

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.

Fitment, availability, fulfillment, and support for this product
The ASV PT-50 is matched to 381x100.5x42 rubber tracks for this application. 100% Precision Fitment. Guaranteed.
Available tread patterns vary by track configuration and jobsite. The options shown for the ASV PT-50 are selected for applications such as construction, dirt, gravel, mud, snow, landscaping and mixed terrain.
Yes. Inspect rollers, idlers, sprockets and track tension when installing replacement tracks. Worn undercarriage components can contribute to uneven wear, poor tracking and reduced service life.
