Air activated sway bar

Ok it may first sound weird but I have all the idea to make it real. The plan is simple, using a air cylinder device to activate or disactivate the sway bar. I want to use the spline on a drive shaft to make it work. I have a 3.5 inch long male spline and the female of the same length in stock that I will weld to my sway bar. I want to cut the male spline about 1/3 of it’s length. I want to drill and tap thread in both part and put a threaded rod between them so they will hold as one piece and still be able to turn freely from each other. So here’s the trick: Using the female spline part I want it to slip over both male spline that will lock both part together. When I want to unluck the sway bar, them the air cylinder will push the female spline off the shorter male spline , this way the sway bar will be desactivated. Since I’m a dealer of air product (valve, cylinder) and having lot a worn drive-shaft it’s something very cheap for me to do. What you guy’s think about my idea?

 

I seem to recall another member engineering a air activated overdrive, maybe they can chime in with tips? I don't any reason why this can't work, just gonna take time to work on, time to perfect.

 

Exact, i'm doing it by lost time, i don't have air onboard the jeep at the moment so it'S not a hurry. Started working on it last night, i cut the spline part of the d-shaft clen everything, drill and tap for 1/2-13 so i can pass a treaded rod all the way in. Finish yesterday by cutting the spline in 2 part. For the moment the female part slide easly over the two piece male spline. I'll try to take some pics this afternoon!
