My Jeep has over 3" of lift (3.5" or so). It's a two-door automatic. I can't go without 4-wheeling much longer. Besides, with the summer coming up, I plan on many camping trips and I want to have some fun with the Jeep too. Right now it's running stock shafts both front and rear. I have front lower adjustable control arms already installed; just ordered rear upper control arms from Northridge to fix the rear pinion angle.

QUESTION: When installing a front driveshaft, do I need front upper control arms too or am I fine without them?

Anyway, there are some very reputable manufacturers out there but I don't know who to really purchase from. I personally have been debating Teraflex vs. Coast, but I am of course open to suggestions and facts. So aside from voting in the poll, feel free to say why a certain manufacturer orwhat you are running and why you went that route and/or how are those shafts holding up for you.

Thanks!

 

Just installed my coast driveshafts last week. I have a 3 inch old man emu lift on my 2 door. I have adjustable uppers and lowers front and rear. I installed the front shaft on friday and drove it home (down the highway at 70 mph) with no vibes. When i did the rear on saturday i got some vibes do to the angle it was at so i adjust the rear pinion angle but no the front. I am getting some interference with the rear jks track bar and the rear passenger side spring (do to adjusting the rear pinion angle) so i ordered rockcrawler coil correction wedges and jks rear spring retrainers from northridge.

 

All the manufacturers you have listed are the top choices, so unless you have a personal preference, any of the listed choices is a quality component. I run J.E. Reel's, however Tom Woods makes about the prettiest drive shaft, not kidding, they are really nice to look at, I'm just saying. So if is pretty is a criteria, then Tom Woods is the winner

 

You'll be fine with just the front lowers. Add the uppers later if you want to move the entire axle forward/backward in the wheel well.

 

What really matters is how it is made. Are they using quality parts to build the drive shaft from, are they replacing the yokes. I think that these companies are all good quality places and more than likely the drive shafts are very similar in construction. You can pay a lot for a name and let’s face it this is not rocket science. Just don’t buy crap to save $50. My vote is “none of the above”.

 

you only need adjustable upper control arms to set your REAR pinion angle. up front, there really isn't a whole lot you can do except find a balance between good positive caster and keeping vibrations at bay. as far as manufacturers go, drive shafts are pretty much drive shafts but, i would recommend that whoever you go with, you ask for spicer u-joints. some of the manufacturers out there use cheap chinese u-joints and i wouldn't waste your time with them. for the affordable cost and the fact that they come with spicer joints, i personally would recommend going with coast.

 

Thanks for all of the replies everyone. What causes vibrations when installing new driveshafts? If I don't have [noticeable] vibrations now with my stock shafts, is it still possible that I may get vibrations with the new ones? If so, why?

Thanks!
