The most up-to-date belt sizing is now available in the Download Instructions section!

Because of accessory variations within model years (different amp alternators, A/C compressor & P/S brands, brackets, tensioners, etc.) belt lengths may vary slightly. The belt sizing we recommend is based on feedback from dealers, owners, and our own installation experiences. These numbers reflect the sizes we found to work in 90% of all installs. To view the belt sizing for your vehicle, please download the installation instructions by selecting the part number from the Download Instructions section.

To better understand how belt part numbers and lengths work we have provided a basic diagram below showing how the part numbering system works. Most brands of belts follow the same basic system, but sizes may vary between brands.
