Installation guidance

Aeroflow Performance does not recommend a single belt length due to the wide range of pulley configurations available today. To determine the correct belt length for your application: purchase the required Gilmer kit, bolt it onto your vehicle, and measure around all three pulleys with the alternator at the lowest adjustment point. This measurement will give you the minimum belt length needed for your setup.
