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 (J or K) 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 + length in mm (e.g. 6PK1200 = 6 ribs, K section, 1200 mm). K section is the modern automotive standard; J section is still used on some models. 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.
