Re: Ball Shifter Force Requirements

Somewhere in the middle is the tipping point between sufficient force and not enough.

Has anyone collected data on how much force is required to engage the ball shifter under load?

Has anyone used a non-pneumatic means of shifting the ball shifters that they'd like to share?
think 67 used window motors one year
