Browse 381x101x42 Rubber Tracks from TrackTECH. This replacement track size supports stable machine control across excavation, trenching, utility work, drainage, landscaping, clay, gravel, and mixed terrain.
Reinforced Rubber and Steel Strength
Premium virgin rubber compounds help resist tearing, chunking, cracking, dry rot, and premature wear in harsh field conditions. Continuous steel cord reinforcement adds internal strength, helps reduce stretching, and supports consistent track stability through repeated loading, turning, and travel.
Precision-Aligned Fit Geometry
Guide lug geometry, steel link spacing, and track body construction are built for direct replacement undercarriage engagement. Proper alignment helps support smooth sprocket contact, stable tracking, reduced vibration, and less stress on rollers, idlers, and sprockets.
Built for Uptime
Heavy-duty construction and jobsite-ready traction help keep equipment productive through long operating hours. The result is a replacement rubber track built for strong value over the full life of the track.
