When installing a new blower belt, don't go wide open throttle for the first hour as the belt needs to break in. Once the belt is broken in you will find that it has stretched, and it will then need to be tightened back down. Do this before going wide open throttle with a new belt, as once a belt slips it is more prone to slippage.

Tell us your application, style and size you want for the pulley when you checkout. Options mentioned above.

Important Information: ProCharger pulleys are available in three different variations depending on the vehicle’s make, model, and year. These variations include non-offset pulleys, offset pulleys, and single-shoulder pulleys.

How do you identify which pulley you have? The easiest way is to reference the chart shown in the product photos or the chart listed below to confirm the correct pulley for your application.

If you’re still unsure, you can remove the pulley currently installed on your supercharger and check how it mounts. A non-offset pulley mounts flush with both shoulders, an offset pulley uses a center post that spaces the pulley away from the shoulders, and a single-shoulder pulley only has one shoulder.

If you’re still uncertain after checking, feel free to email us a photo of your pulley or provide your ProCharger supercharger application, and we’ll be happy to help identify the correct pulley for you.
