With this rzeppa on a 3.5" lift jk & stock front drive shaft, do you still need exhaust spacers? any high speed speed vibrations from the driveshaft?

Yes, you need spacers. I have their spacers on mine, same lift height, and my driveshaft will still contact the exhaust at full extension. I haven't noticed any vibrations compared to stock, definitely not compared to the Tom Woods shaft. I'm also running 5.13 gears, so my driveshaft spins much faster than stock. Hope this helps.

What is the maximum working angle of these joints?

On my JK, lift 3.25" - works fine!

I have the usual vibration after lifting my 08 jk 2.5" and 33" Duratracs. Is there anything else needed to get the job done?

I don't know about"usual" vibrations, I'm lifted 3.5" and on 37" BFG KO2's, had no vibrations. The rear joint on front shaft splits the boot when lifted. The Teraflex joint is a simple and easy way to upgrade. Nothing else needed.

will it work on my 2 door 2008 jk jeep manual? It has a 4 inch lift kit, do I need any additional parts?

With that much lift you might need a new driveshaft for that kind of lift especially if on 35’s or 37’s. I’m at 3 in the front and it’s pushing it. Also getting adjustable front lower control arms to help with driveshaft angle will be really helpful. I have a 07 2 door on 35’s so same Jeep pretty much
