What Goes Into Every UltraTrack Track

Every UltraTrack rubber track is engineered with a multi-layer construction system designed for maximum service life under real jobsite conditions.

  • Continuous Steel Cord Belt — A single continuously wound steel cable runs the full length of the track, eliminating splice points that cause premature failure. This is the same belting method used in OEM tracks.
  • High-Tensile Steel Links — Drop-forged steel links engage cleanly with your machine's sprocket for smooth power transfer and reduced undercarriage wear.
  • 100% Virgin Rubber Compound — Acid-washed steel cords are bonded through multi-stage vulcanization. No reclaimed or recycled rubber. The result is a track body that resists delamination, cracking, and chunking even under sustained heavy loads.
  • UV and Ozone Stabilizers — Built-in antioxidants and antiozonants protect against sun and weather degradation, extending track life for machines that sit outdoors between jobs.

Track Care: Getting the Most Hours from Your UltraTrack Tracks

  • Tension Check — Check track tension at the start of every shift. Over-tensioned tracks accelerate wear on sprockets and idlers. Under-tensioned tracks risk derailment. Refer to your your machine's operator manual for the correct sag measurement.
  • Clean the Undercarriage — Packed mud, rocks, and debris add weight, increase fuel consumption, and cause uneven wear. Hose out the undercarriage at the end of each day, especially in clay or mud conditions.
  • Inspect Wear Indicators — Look for cracking between lugs, exposed steel cords, uneven lug height, and missing chunks. If the rubber between lugs is worn to less than 1/4 inch, it is time to replace.
  • Rotate Travel Direction — When possible, alternate the direction your machine travels on repetitive routes. This distributes wear more evenly across the track surface.
