FleetRunner Heavy Duty Micro-V
Gates® FleetRunner® Heavy Duty Micro-V® belts are engineered to save your fleet money and lost service time. Patented EPDM construction with distinct green overcord built specifically for more durability, superior flexibility, stability, and longer life on heavy-duty drives. Haul more. Drive longer.

Features & Benefits:
  • Patented material provides peak performance at prolonged extreme operating temperatures.
  • Heavy-duty construction resists cracking and wear, even at extreme temperatures.
  • Special compound provides unmatched flexibility, stability, load carrying capacity and belt life.
Service Tip: Always replace belts and tensioners together. Old tensioners will reduce a belt's lifespan, and can lead to issues such as overheating, a dead battery, diminished power steering, or poor air conditioning performance.
