Re: speedometer cable install

That's all you do. It did line up with the gear in trans. and the back of the speedo didn't it.

After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.

Re: speedometer cable install

I am getting ready to do this to mine.. Mine wasnt hooked up when I got it so I assume something is messed up.. I guess I will just pray my internals in the tranny are good.

Good Luck with yours I hope you get it working.

Re: speedometer cable install

Assumimg he got the right cable. Assumimg he can see the back of the speedo... which most can't. I would check it. Make sure it's tight and pulled all the way up.

the speedo gears in the tail shaft are easy to replace. remove drive line, disconnect speedo cable. remove 4 bolts from tail shaft housing and remove. there is a small clip that holds the drive gear for the speedo to the shaft. press down on the clip and slide it off. the cable gear is just a pull out from the cable housing.
