Product Details

The Gates K100456HD FleetRunner Micro-V Belt is a heavy-duty, ribbed serpentine belt engineered for demanding commercial and fleet vehicle applications. Built to Gates' exacting standards, this K10 section belt measures 1-3/8" wide × 46-1/8" long and delivers reliable power transmission across multiple engine accessories.

Key Features:

  • Heavy-Duty FleetRunner Construction – Designed for high-mileage commercial, fleet, and heavy-duty applications where standard belts fall short
  • Micro-V (V-Ribbed) Profile – Precision-molded ribs provide maximum surface contact with pulleys for efficient, slip-free power transfer
  • K10 Section – 10-rib configuration measuring 1-3/8" (34.9mm) in width
  • 46-1/8" (1171.6mm) Effective Length – Consistent sizing for precise fitment
  • EPDM Rubber Compound – Resists heat, ozone, and cracking far longer than traditional neoprene belts
  • High-Tensile Cord – Reinforced tensile members maintain belt integrity under heavy accessory loads
  • OEM-Quality Replacement – Meets or exceeds original equipment specifications

The Gates FleetRunner line is a purpose-built solution for trucks, buses, motor coaches, and other fleet vehicles that require maximum durability and extended service intervals. The K100456HD is a direct OEM-quality replacement serpentine belt suitable for heavy-duty accessory drive systems.
