Product Details

The Gates FleetRunner Heavy Duty Micro-V Belt line is engineered for commercial and high-load drivetrains where belt consistency matters.

What This Belt Helps Address

• Squealing or slipping caused by belt wear
• Cracking, glazing, or rib deterioration on the drive belt
• Loss of belt tension stability in heavy-duty service
• Reduced accessory drive performance under sustained load
• Downtime from premature belt replacement intervals

Installation Notes

Verify belt routing, rib count, and effective length before installation. Inspect pulleys, tensioners, and idlers for wear or misalignment, since those conditions can shorten belt life. Confirm the supercharger application on the vehicle before ordering, especially on 2023-2026 Dodge Durango and 2018-2021 Jeep Grand Cherokee models.
