Thanks for bringing that up, I wasn't aware of that and did a search on the issue and found that it looks like some people with mid-arm and long-arm suspensions may still need a new drive shaft, or a different solution.
To clarify to anyone reading this, I have a 4.5" AEV lift with new Tom Woods drive shaft that is thinner. I still stand by my recommendation of this as, even a permanent solution, as it works with this setup (but my recommendation is with this setup alone). I have completely maxed out my suspension and gotten the Jeep on 3 wheels with no issues. However, this is the case on my specific application, and if you're using something else, YMMV in some cases.
I think, however, for those that are reaching the end of the money roll, that putting the extra money you saved on this vs the Y-pipe towards a new front DS is definitely a good move. That driveshaft even on 3" is going to get stressed quickly.
That said, if price wasn't a consideration, I would definitely have gotten the AFE Y-pipe since its the cleanest solution (and now enough people have reported no power loss on the butt dyno
then back when I decided). Though, as I finish up my mods and more money frees up, I don't think I will go back and get it now for my application since the spacers worked out so well and there was no performance loss at all (on the BD).
