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.
