Gates 9305HD/13A0775 Fleetrunner Heavy

Gates Fleetrunner Heavy Duty Micro-V belt, HC 50 section — an EPDM-compound serpentine accessory-drive belt built for large-displacement heavy commercial vehicle engines that use a wider HC-section pulley rather than the standard automotive K section. Sold under the Green Stripe FleetRunner name.

Where this product is used

Gates Fleetrunner belts drive engine accessories on trucks, buses and coaches — not passenger cars or industrial equipment. Typical uses include:

• Alternator, power steering pump, air conditioning compressor and water pump drives on heavy commercial vehicles
• High-mileage, continuous-duty fleet and commercial vehicle applications
• OE-equivalent replacement on scheduled heavy-vehicle services

Key specifications

Selecting the right option

Select by belt section and rib count to match your vehicle’s original belt, or cross-reference by Gates or OE part number — the code reads as ribs + section letter(s) + length in mm (e.g. 6PK1200 = 6 ribs, K section, 1200 mm). K section is the standard automotive fitment; wider HC sections appear on some large-displacement heavy-vehicle engines. Looking for an industrial Micro-V belt instead? See our industrial Micro-V range. When in doubt, contact AIMS — we’ll confirm the right cross-reference for your vehicle.
