Description

Gear used in the blend door actuator of many GM vehicles from the 90s to 2000s. Picture has the gear installed in the actuator from my Blazer.

Printed in PA6-CF, which is arguably not the best gear material due to abrasiveness , but was the strongest I had on hand. Not sure of the long term performance.
