I try to avoid jam nuts myself. Looks like he already ordered it. He'll be fine .. A lot of folks run JKS. I'll have to look into the bushing upgrade. Edit: hmm looks like it can be run in stock and other track bars as well. Good choice ... News to me. Thank you !!!
Something to keep in mind ... Not all track bars adjust to stock if used with a track bar bracket (steering correction or high steer kit)

MnJK Planning to upgrade the stock front track bar and am leaning toward the JKS adjustable. Seems like it receives consistently positive reviews, can be rebuilt and I like the way it adjusts compared to the Teraflex, for example. The track bar has the option of standard bushing or upgrading to the "SuperDurometer" bushings. Found just a few threads and all went with the upgrade. I just have a small lift now (1.5" performance leveling lift) and 33's.

Off-roading is wooded trails, off-road parks with rock crawling on "difficult" rated trails. Definitely not expert trails with large obstacles as my set-up doesn't have the clearance and I'm not at that skill level (yet!).

Lastly, I'd like to be able to stick with it over time through future upgrades (max lift will be 3.5" with 35's) and the JKS seems like it could handle that just fine.

So, now the questions....
Any known issues with this product?
Would work well over time as mods grow?
Upgraded bushings seem like a good choice?

Much appreciated!

The upper arms will allow setting caster/pinion angles which you won't get with the basic TF 2.5 kit.

It's a toss up between TF/Rancho. Contact the Rancho rep. See if he may have a idea on the rebate.

The grease comes from the other rubber boot. Front shaft at the transfer case. Rear the same although there's a joint on both ends.
The excessive angle can split the boot and throw grease.
The boot you tore is just a dust cover correct

How about any of the 2.5" budget boost lifts ?
TeraFlex JK Wrangler 2.5 inch Performance Budget Boost w/Shock Adaptors - RockRaider Off-road

This is just a example. There's kits with new shocks, without shocks (choose your own)

At most, maybe a set of front lower Control arms or drop brackets to correct caster angle and improve handling.
I was looking at a suspension lift but I don't know much so if thats what you recommend I'll definitely look into them more. Thank you!

A little advice.
I tried adjusting my tie rod yesterday. the adjuster was frozen pretty good. I damaged a tie rod end boot trying to rotate it.
You'll notice when you receive the track bar (or any other Synergy part I'm sure) there's Anti seize on the parts but metal burrs/filings everywhere. I love Synergy's stuff ... But that's just Poor quality on their part.
This is what I did with my track bar.
Remove the joint and quick adjuster sleeve. Clean off all the Anti seize. Use a file and Dremel to clean up all the burrs/metal left from machining. I wire brushed everything before install too. Just make sure everything is smooth with no burrs and metal chips. Finally, re-coat the threads with Anti seize and reassemble.
Hopefully I won't have the same issue with my track bar as I did with my tie rod in the future.
I also started using Fluid film on all my joints. So far 0 rust on any metal surface. Great stuff ... Works as a lube to on heim joints.

May want to check with somebody that's been running it for a while. See if there's any settling.
That would be what I would recommend for you,
The 9000's would certainly help with brake dive, overall handling,
Maybe instead of buying a leveling kit ... Piece together something, 1" all around if you want to keep the rake but stay Low.
Actually .... Google Daystar. I believe they make a 1.75 kit .. The front spacers are a bit taller but not 1" like most leveling spacers,

I give you mad credit for reading this whole thread lol
Thanks for the feedback. One follow-up question for you - any thoughts on the spring swap? Might 17/59 get me pretty close to my target or is it just too much of a crap shoot? I assume most of the variability in results with the spring swaps people report are due to differences in added equipment and not because the actual springs are delivering inconsistent results. I'm optimistic that WhiteWillysJK's results are close to what I'd get given it's the same Jeep without any add-ons.

As a side note, I can get 16/58 springs pretty cheap but it may not be a big enough increase in the compression rate to deliver a meaningful improvement. Agree?

AGS Phew! It took a few sessions over a couple days but I made it through all 2,100 posts across 70 pages. Theres a wealth of knowledge in here which really helped me think about my situation. Plus, I knew my post was going to be on the long and detailed so I felt I owed it to the regular contributors to this thread to read all the advice that had previously taken the time to write. Anyway, here we go:

What I have: 2014 JK Willys Wheeler. Ive done a few minor mods, but the only one that impacts this discussion is the TeraFlex 1.25 wheel spacers I added to push the wheels/tires out a bit to better fill the fender flairs. I have no plans to replace the stock bumpers, so no added weight front or rear. The stock springs are 13/56.

How I use it: The Wrangler is the weekend fun car for my family. I have two young boys and they love driving around with the top and doors off. The Jeep will likely spend 95%+ of its time on-road, but may see some occasional light off-roading. Unfortunately, the closest state park with trails is almost an hour and a half drive so frequent off-roading is just not in the cards right now. It will also come in handy on snow days as a substitute for my daily driver.

What I'd like: Id like to add a little bit of lift, ideally something in the range of 1 to 1.5, primarily for the look but also to accommodate slightly larger tires. From reading this thread, I know the stock setup can handle up to 33 tires, but for aesthetic reasons Id like to maintain the gap between the tire and the fender flair (I dont like the squashed look of the wheels completely filling the fender flairs). As far as tire size Im thinking something in the 33 to 34 range, but not bigger so I can avoid performance issues given the 3.73 gearing. I took a bunch of different measurements yesterday and found my Jeep has about 0.5 of rake, which is not really noticeable to the eye. It seems most kits (whether leveling, lift, etc.) incorporate 1 more lift in the front to eliminate rake and account for additional bumper/winch weight, so Im nervous about doing any sort of lift that will result in a nose high stance on my Jeep given the lack of added weight. Separate from the lift Id also like to reduce/eliminate the squat and dive the stock setup experiences on hard acceleration and braking.

Id appreciate any suggestions/advice from the experts on this thread. Here are the potential solutions Ive come up with:

Coil Spacers Probably the simplest way to go because it they deliver precise results. In a perfect world Id add 1.25 in the rear and 1.5 up front, but nobody offers spacers in those sizes - the only choices are 1 or 1.75 (I know, Im being really anal over fractions of an inch!). Also, I lose about 0.5 to 0.75 of height when naked vs. fully loaded with hard top and doors, and the spacer solution does not remedy this at all.

OEM spring swap Swapping to slightly stiffer springs will help reduce the height loss when fully loaded and give me a little lift. The issue is the results are unpredictable. Ive seen a few posts from members who went to 19/60 and picked up 2 or more of lift, which is more than Im looking for. However, in post 2,045 WhiteWillysJK (same Jeep as me) went from 14/56 to 19/60 and got 1.75 front and 1.25 rear. This gives me hope that going from my 13/56 to either 18/60 or 17/59 will get me very close to my target.

For either of these first two solutions Ill also need to upgrade the shocks to address the squat and dive. I know kjeeper10 loves the Rancho 9000s I assume Ill see a noticeable improvement in ride with this upgrade from the Rubicon shocks that come on the WW?

The Last option is the Rancho 2 Sport lift kit. The benefit of this solution is that it delivers the lift and shock upgrade in one complete package. The potential issue is that with no added weight, I could end up with a lot more than 2 of lift, which was already a little more than I wanted to go.

Thanks for reading, and thanks in advance for your thoughts and guidance!

Yea, that's what I was getting at. The AEV 2.5" lift instructs you to unclamp the brake/abs lines from the coil perch. I wasn't aware 2012+ had longer lines.

Couple questions:
What are the stock brakeline lengths?

Should i get lines that are extended the same amount if lift i have? (Example: 2.5 inch lift, do i need lines that are 2.5" longer than stock?

Why are these:

Crown Performance 5 Layer Custom Brake Lines | Jeep Parts and Accessories | Quadratec

More expensive than these:

I think you have a new rubicon if I remember correctly. Your stock brake line is plenty long you just need to get a terra flex brake line relocation bracket and bend the metal part of the line a bit. make sure you do something with the parking brake line and the abs sensors. on the sensors just pull the fir tree clips on the zip ties so they can hang freely. I have had mine max flexed and the brake lines have several inches of slack the parking brake cables however do not.

08-21-2014 02:57 PM
kjeeper10 I run Synergy's in the front.
One size fits all .. 2.5-4" I believe.

Best way is cycle the suspension. Hight/extra shock travel will determine the lengths needed.

Did you disco the lines from your coil perch ?
