Wanted to share some feedback the shop gave me regarding the BB.
First off, they had a lot of nice things to say about it, liked the quality and fit, etc.
But they did make two recommendations which I wanted to share:
I had him add Rubicon take-off shocks and 18/59 springs. He wasn't too thrilled with the shock adapters and the stock connection, and recommended Bar Pin Eliminators, JKS for example.
Also, he said there was some pressure/tension on the track bar and strongly recommended an adjustable trackbar. Here's another JKS shot.
That's all I have. Oh, and it turned out that there were many questionable hand-tightened bolts under there, which he torqued. Go figure.
You mentioned in your original post that you put on a 2.5 spacer lift and added 18/59 coils. The coils or "springs" would have netted you a good bit of lift by them selves. Putting these on with the spacers is going to add much more than 2.5" of total height to your lift making you cross over the threshold of tolerance for your drive shafts.
You should watch your front shaft carefully for signs of grease spitting or failure from now on. It's going to fail if you really did combine these.
And here I thought I was tracking this, knew that more than 3" was problematic, but -- again, blame it on ignorance -- didn't expect the springs to contribute much on a JKU.
So, believe it or not, I was very surprised at the height and was hoping it might all just settle down a bit. (Does that happen?!?)
Here's another thought: What if I added an after-market bumper to the mix? Would that extra weight compress things back into a zone where I don't have to worry about busting a DS?
I just ordered the adj track bar and pin eliminator -- so I'll do what I have to do to make my Jeep right, haha.

Yes... That was part of my issue, no weight . TF's coil lift does 3" and 2"
My jeep was popping a squat so I added 1" rear spacers. Now my jeep averages more than 3" and my front DS lost some grease already.
Lift manufactures give you a little more in the front for heavier bumper/winches.
My friend who did 19/60 + BB did AEV's brackets which helped.
I would probably benefit a bunch with some added weight.
You too ESP :whistling:
Great. Now I am subscribed to the What-Happens-to-Your-OEM-Driveshaft-When-You-Put-a-3"-+-Lift-on-Your-Jeep thread. And I am going to search for the Ultimate-bumper thread, or whatever it's called.
Something tells me my wife is going to lose it if a new DS and bumper show up on the porch, haha.
I was originally interested only in something like this WARN:
But will probably check out some full-sized ones now too.
You've got a 4 door. A 3" puck up front isn't going to compromise your driveshafts--I've got a 2.5" coil lift (3" up front, 2" in the rear) with stock bumpers and my driveshafts are fine.
You added some relatively high gauge stock springs too, but, again, you've got a 4 door. What were your original springs? They might've been the same. When I added 19/60s they gave me MAYBE half an inch over my original 17/58s. Almost inconsequential really (hence pulling them out for a real lift).
Just poke your head under the jeep periodically and check your shafts.
I can honestly say I've never heard of someone having driveshaft problems off a 2.5" budget boost. I predict no problems.
I think all this is a little overblown... I can honestly say I've never heard of someone having driveshaft problems off a 2.5" budget boost. I predict no problems.
Yea, just gonna stay on top of it and watch out for problems.
Worse case scenario, I'll deal with what happens.
But honestly, the lesson I learned here -- and it is a surprising one for me -- is that it is so easy to get lift. I mean, my original springs were 16/58s, so I wasn't expecting much.
Anyhow, for now, it is what it is. In the mean time, barring some disaster, I am enjoying the lift. I have the quicker discos still to put on, and now have the adj. track bar on the way (and that pin elim, for what it's worth).
Just curious for discussion purposes, but if I have Dana 30/44 right now, is it realistic to upgrade the front axle to something like a 44 or larger up front?!? And the gears would have to match, front and back, no. I really know nothing about this, haha, but an eager to learn.

I had the 19/60 coils with 2" spacer. All I needed for that was Cam Bolts and shocks. Didn't need adj. track bar. Not that I couldn't use them just not a have too.
To be honest, I hated the feel up front with this set up. The 19/60 coils are stiff and adding the spacers just seems to make it feeel even stiffer. I also had a popping noise develope in the front end. I ended up taking this out at least up front 1 month later and replacing them with 3" coils. Didn't need anything else since the 19 coils with spacers were a little over 3" anyways.
Much better ride with the 3" front coils then the 19 factory coils with 2" Teraflex spacers. Not saying it won't work, but I bet you will regret it over time. I did. The 60 rear with spacer are just fine. It was the front that was the issue. I got 3" BDS coils for $110 at my local off road shop.

I'll definitely keep that in mind. And you're probably right -- I am just caught up in the same vicious cycle that many on the forum are caught up in: mod, mod, mod.
They go in the ends of the front axle tubes and keep mud, water, sand, etc out of the axle tubes.
Are you running stock Rubi shocks with this BB? You realize the bar pin eliminator doesn't really extend your shocks? Just a different means of mounting them.
First I heard of using bar pin eliminators on a JK
but I'm no expert. Adjustable track bar, I can see that.
Now I need more stuff if I go for 35's, LOL. Those axle seals look like they would be very useful.
You should contact Chris at Jeep Add-ons or Truck ad ons (vendor here) and see about the axle tube sleeve kit and inner c-gusset kit with lower control arm skids. Seems like a good deal to me.
Should also note I know 2 guys with 35's and 2.5" BB's. Both use the shock extensions and have had no issues. One RC kit, the other Teraflex. I suppose a little extra insurance can't hurt, especially if you play on the rocks a lot.
