17 rcsb 2/4 drop vibration
I just lowered the truck and am having a vibration issue on acceleration from a stop from about 15-25mph. This is a 2017 5.0 rcsb, anyone else come across this? Im thinking i need a different pinion shim than what came with the kit, anyone know the stock pinion angle/driveshaft angle.

I haven't looked at a truck like yours. Does it have a two piece drive shaft? Here's some reading for you:

The truck has a one piece drive shaft. As far as i know its identical to a 2016 model. I read that thread already and sevetal others but havent found one specifying a 2017 rcsb. The instructions said to install shims with fat side forward so thats how they went in.

Ill look for an app if not ill just go buy an angle finder. For the mean time does anyone have a pic of the stock pinion angle just to make sure im headed the right direction. I beleive the shim that went in there was a 3 degree shim

So i got an angle app. I placed phone on pinion flange and then on flat surface on driveshaft. The difference is 8 degrees, I would need a taller shim than what i have there to get me to the 3 degrees. Im assuming that driveshaft collapses correct?

I would reallyreally like to see a picture of the drive shaft set up, if you have time. Converting to a one piece drive shaft is an idea I've been considering for a while and I would like to see how yours is set up.
