Read this entire thread over the long weekend. Lots of really good information, and I thank the contributors.
I am seriously thinking about changing tb bolts. I inquired at my dealer, and they refused to install any non-Mopar part.
I am a bit reluctant to tackle this on my own because I am not sure how to remove the stock bolts and then torque the new bolts to spec in the tight confines of the underside of the jeep. Perhaps the jackstand options will allow more leverage, but getting the proper tools into the tight areas looks daunting. Perhaps I am making this harder than it really is considering how many have successfully done this mod.
I think my first step will be to try and torque the stock bolts to spec. I suppose that if I can do that then I can tackle the bolt replacement.

|Tink5775||KPM171 - there has been a change in the Northridge kit since that was posted. They've added 2 14mm bolts and lock nuts to replace the Front Track Bar Frame Side bolt on 11 & 12 JKs.|

Read my post on the Northridge bolt kit.
Today 2480 easy miles on our 2014 JKUR, our dealer installed the Northridge kit.
The bushings were scarred from the all thread stock bolt.

Okay, it seems like only one bolt is undersized...and I don't feel like replacing other bolts that don't need to be replaced.
So, can someone please tell me the dimensions of the bolt that needs to be replaced and the dimensions of the bolt that it should be replaced by?

|RubiNewb||I got this done last night. Raised the Jeep on my brother's lift and used an air ratchet which made things go much easier and faster, although we did end up stripping one of the new track bar bolts, but luckily we had extra because my front track bar used the 14mm bolts. I have 28k miles on mine and have been off-roading about 5 times but nothing too major like serious rock crawling etc. and did not notice any damage to the bushings except on the front track bar where we encountered the longest holdup because the bushing sleeve had a bur in it which made getting the bolt in really fun. All of my bolts were really tight from the factory except the front track bar bolt driver side. I still have no clue why the factory put threaded bolts on the suspension parts. Seems like a simple and cheap thing to do to just put shouldered bolts from the factory.|

That works. 8 lower CA bolts (longer) and 4 track bar bolts (shorter) Front upper may need 14mm depending on bushing/year.
Remember to replace the bolts in one arm at a time and leave loose. Replace 4 track bar bolts but leave loose.
If installing a lift also, loosen uppers but don't remove.
After all done. Install tires and lower to ride height. (You can also support at the axles for more room)
Give the jeep a good shake letting the bushings set to their new positions. Torque to spec
Lower CA's all 125
Rear upper CA's 125
Front upper CA's 75
2 track bars 125
I found a long breaker bar like this one from harbor freight helps w/ solo torquing. Anchor against the ground to hold the bolt head from spinning.

So for the greater good of the forum, I made another picture, hopefully I did everything correct. Let me know if I made any errors, but I think this will help everyone visualize the bolts that need changed.

Just to clarify, the basic kit, for the LCAs and TBs, is replacing the bolts I circles below, correct?
And in that pic, where do the smaller bolts go? I bought the Synergy kit last night.

Note: The 2012 front TB has a bearing joint on the frame side attachment point (Front Driver Side) that the 9/16-18 bolt, from either kit, will not fit through
Just wanted to make sure I DIO & DIR!

According to this just the front, however I believe it was just 2014's:
|06-03-2014 10:04 AM|
Front or rear?

|RubiNewb||Need help, the 8 longer bolts are for the lower control arms, the (4) 3" bolts are for the front and rear track bar...what are the two zinc bolts for? I have the Northridge kit but newbied out when I laid these bolts out... Thanks!|

This looks like a good route for those wanting to just do the minimum...

The uppers are overkill IMO .. Hell even CA's for most people. The 2 front track bar bolts are the most important because of death wobble. Grade 9 is overkill .. The tinsel strength between grade 8 and factory 10.9 is the same. Being "stronger" has nothing to do with the thread in general. Slightly bigger and the shoulder help fill the hole and prolong bushing wear.
Like I said already ... I did have a rear CA loosen to where it was clanking around. A friend was hearing some noises and stopped by. Running the geo brackets all but 1 driver side CA bolt was tight. 1 was about to fall out. She did note a tighter steering feel but no big issues.
Now if a front track bar bolt were to loosen, I almost guarantee death wobble.
Crap ... If I were to do it again. I would just source 2 fronts and call it a day.

What is everyone's opinion on the various kits? From what I understand, the Northridge Grade 8 kit is the minimum, does the TB and the LCAs. Is it worth it to spend the extra $40 or so on the Synergy kit, in order to get the harder bolts?
And even above that, is it worth it to replace the UCA bolts, which would require the full Synergy kit? My research has lead me to believe the UCA bolts aren't really an issue.
