Gates K080485HD Serpentine Belt

Heavy-Duty Micro-V Belt for Fleet Drives

The Gates FleetRunner Heavy Duty Micro-V Belt is built for accessory drive systems that see constant load and long service intervals. This K080485HD serpentine belt uses EPDM construction and a polyester cord for durability, flexibility, and stable operation on heavy-duty drives.

For fleet maintenance, the Gates K080485HD helps reduce downtime by delivering an OE-improved belt design with a distinct green overcord for quick identification. It is a strong choice for heavy-duty belt replacement on vehicles such as Ford F-150 and Chevrolet Silverado applications that use an 8-rib K-section belt.

FleetRunner Belt Line Details

Gates FleetRunner Heavy Duty Micro-V belts are engineered for demanding commercial and fleet service. The line uses patented EPDM construction and a green overcord to support longer belt life, better flexibility, and consistent performance on heavy-duty accessory drive systems. The Gates K080485HD follows that same heavy-duty design approach for applications that require dependable serpentine belt operation.

Detailed Description

This serpentine belt is designed for accessory drive systems that need a durable, stable, and dimensionally consistent replacement. The K080485HD measures 48.59 inches in effective length and 49.125 inches in outside circumference, with an 8-rib profile and K cross section. Those specifications make it a direct-fit style option for vehicles using this belt size, including Ford F-150 and Chevrolet Silverado fitments where the accessory drive depends on an 8-rib heavy-duty belt.

This part cross-references Dayco 5080485 for the same application.

What It Helps Address

• Squealing or slipping from a worn serpentine belt
• Cracking, glazing, or rib wear on the accessory drive belt
• Loss of belt tension stability in heavy-duty service
• Premature belt replacement caused by heat and load cycling
• Accessory drive noise on fleet and work-truck applications

Installation Notes and Tips

Verify the belt length, rib count, and section designation before installation. Confirm the routing path on the accessory drive system and inspect pulleys, tensioners, and idlers for wear before fitting the new belt. For Ford F-150 and Chevrolet Silverado applications, match the belt dimensions to the original equipment specification to ensure proper tracking and tension.

Quality Assurance

Gates designs FleetRunner Heavy Duty Micro-V belts for demanding fleet use with EPDM construction, polyester cord reinforcement, and an OE-improved design standard. The green overcord helps identify the heavy-duty belt line during service and replacement.
