hey all. Im about to lift my wrangler ( gotta love tax season)
Ive done all my research and documented it. I would love any advice .
Heres the info (sorry for the length)

Lifts


http://www.aev-conversions.com/shop/shop-by-category/suspension/jk-dualsport-sc-suspension.html

This kit is supposedly one of the best on road rides, they say it performs better than stock. only complaint is it uses brackets and the stock control arms, which actually lower the arms down compared to just replacing with stronger ones. comes with bilstein 5100 shocks that are supposedly engineered specifically for this kit.


http://www.rockkrawler.com/ProductDetails.asp?ProductCode=RKJK35MT

this kit is alittle more money, in all the forums they reference rock krawler as being far superior to the aev. But thats usually people who actually dont have the aev..
All parts included in this kit come with a lifetime warranty also. Only two things you need to buy separate are the bumpstops and shocks. They have cheaper versions of this kit but this is the most complete and from what ive seen people end up putting on everythgin included in this kit eventually anyways. This kit is all bolt on but they recommend welding the brackets at a few points. Also comes with brake line extentions compared to aev just using the stock brakelines with a bracket.

I was looking also at RANCHO and Rough Country but people say their springs sag or they have issues with control arms or other parts. People say they like them but eventually replace them for something stronger.

Driveshafts :

For driveshafts the three major ones are
tom woods

coast
http://www.coastdriveline.com/DriveShafts.htm
and j.e. real
http://reeldriveline.com/catalog/fr...s-p-37.html?osCsid=gcg44b3o6cv31gncn1v7b2lqh4

all three are about the same price.


So to summarize, I am definitely going to go with one of the kits. Im honestly thinking spend the extra few hundred for the RK kit. I do 90% on-road right now for work, with off road almost bi-weekly for a few hours. If i get the aev, i know when my daily driver becomes my toy though i will probably upgrade anyway. Spend the money once and save the hassle.
first hand experience on road for the rock krawler would be nice. Ive read the handful of aev vs rock krawler threads but with no definite answer as to on road quality of the RK.

so the big questions :
what driveshaft company would you use and what lift would you pick in my situation.

Thanks all in advance,
Jason

I went with the Rancho 4 inch sport kit knowing I would be upgrading over time as money would allow. The Rancho kit was very good quality IMO and I'm still running the brake lines, springs and RS9000XL shocks. I have had no sag and have not heard of complaints about sag. I don't plan on replacing the shocks or springs and prefer the shocks over the Bilsteins on my F150.

I have since replaced the drop brackets. I have Teraflex front lower, RK front upper and RK rear upper and lower mid arms.

I also replaced the front track bar and rear track bar bracket. I have Poly Performance front track bar, front track bar bracket, drag link flip, sector shaft brace and upper track bar bracket. In the rear I have rear JKS track bar bracket, adjustable spring perches and Poly Performace track bar.

My rig rides and handles great!! Except for the rear lowers I bought all of the control arms from forum members.

I have Adams drive shafts. The front is not mounted(I'm chasing a vibration and don't want another variable), but the rear is and it's smooth as butter. The Adams shafts are great quality a far less expensive than most shafts.

I have a 2 door and if you have a 4 door you can put off drive shafts for a while with the Rancho kit and may not need the rear spring perches or to replace the Rancho rear track bar bracket(it would not work with the adjustable perches).

I prefer the Poly Performance parts listed above over the RK stuff.

I have a Franken lift I'm very happy with, built with the specific parts I prefer and I spent less than If I bought the entire RK lift.

Just install a budget boost and call it good until you know what you want to (really) do with it. No since in blowing a wad until you have it all figured out.

Need some more details:
2 or 4 door
Intended tire size

I run the Coast front DS, no issues.
Just an FYI you can run this budget boost with 35s. (requires just wheel spacers, bump stops and a little fender trimming)

We definitely need more information on whether you're in a 2- or 4-door, how much tire you plan to run, and where and how often you'll be wheeling.

As far as the Rock Krawler systems, we've found that a lot of off-roaders have been more than satisfied with the RK 3.5" Flex System for 4-door JKs. It's at a great height for 35s and stock flares while not looking awkward on flat flares, and provides more than enough articulation for most users. The 3.5" Max Travel System is great, but unless you're an avid wheeler hitting the trails every couple weeks, you'll honestly probably not notice the difference.

If you're in a 2-door we usually recommend the 2.5" Max Travel System or the 2.5" X-Factor if you want to play it safe, since the 2-doors do get a bit more lift than the 4-doors.

On the driveshafts, don't forget about Adams Driveshafts. 100% American-made with 100% American parts... and a significantly better price than the others you mentioned. This is what we're running on the front of our 2012 and it's held up to some unjustified abuse during the last year with zero indications of surrender. Once the one tons go in we'll be running their 1350 style driveshafts front and rear.

thanks everyone for the posts so far. Sorry for the delay in response, the dam thing called work got in the way..

I realized after i posted i didnt give any info about my rig. Its a 2012 2 door wrangler sahara.

Right now its majority daily driver, but i do go wheeling , and when i have it lifted and capable of handling alittle more abuse im sure ill be taking her out more. But my ultimate goal over the next few years is to make this my toy and aquire another wrangler as my daily driver, and the let the cycle continue. At that point im going to be taking this out even more, so id rather lift it and have it done right and full, and save the money down the line. (with the understanding that no matter how much i dump in now i may need to add more , change something, or upgrade something down the line)

Some comments from your guy's posts

I actually remember seeing something about the adams driveshafts. Let me look into them more!

Looking at the teraflex it ended up being around the same money wise and for the quality the RK kit looked more worth it.

TERRAHAWK
As for the budget boost; id rather just wait until i decide and do it right. no point waisting any money for a temporary solution. Do it right the first time.


ASSFROW
The rancho kit definitely did look good, but as you say in your post you've already replaced parts such as upper and lower arms, I want to replace these from the get go, looking at your parts list, youve pretty much spent the amount for the whole RK kit anyways. I may be off by alittle but just an observation. Please correct me if im wrong!

I feel differently about the kits. I think the high steer in the Max Travel is a huge benefit on the road.

I went a different route because I prefer parts that don't require welding(RK kits require welding). I can't weld and don't have access reasonably priced welding and prefer doing things myself.

OP, what tires do you want to run? You'll get roughly a 3.5" lift from the Rock Krawler 2.5" coils. The 3.5" springs will allow you to run 37s. Most of the 2-doors I've dealt with have been extremely satisfied with the 2.5", to then swap to 3.5" coils when they do step up from 35" to 37" tires.

For a point of reference, here's a customer's rig on a Rock Krawler 2.5" Max Travel we installed. He has trimmed stock flares and 33s...

I do agree that the steering upgrade is a huge benefit once you hit 3" or more.

The Rancho kit is similar to the AEV kits. It doesn't come with arms and uses drop brackets. As for the money I spent less, because of how I got the parts.

I prefer the Poly flip kit and track bars to RKs, so a full RK kit wasn't the right choice for me. I also don't like RK's track bar brackets. I chose the Rancho kit, because I didn't plan on doing arms and everything else as soon as I did.

With all that. I wouldn't recommend the Rancho 4 inch kit for a 2 door. It's way too much lift unless you plan on doing a ton more work. If I were to do everything over I would still build a Frankenlift. I would just do it a little different.

OP of you have any questions about out products let us know.
A few things to keep in mind:
Made in the USA.
Lifetime Warranty on parts as well.
Great product for the price.


Sorry you feel that way, in our experience this NOT the norm.
Rancho has the Midas touch, only everything they make (touch) turns to shit instead of gold.

You are completely wrong. The kit was very well made and very complete for a drop bracket kit, but it gave me about 5 1/2 inches of lift on my 2 door. If it were a true 4 inch kit it would be great after adding bumpers, carrier and a winch. There are tons of JKURs running this kit for a long time that are very happy.

I'm still running the springs and shocks and they work great.

Thanks for concidering RK for your build. Is your JK a 2 door or a 4 door? What size tire do you plan to run and what size tire do you eventually want to run if you are planning on upsizing your tires down the road with flat fenders or some other options?

I've run the 2.5 X-Factor on three different JKs now, two of them being 2012s.

This is my 08 with 2.5 X-Factor, Poison Spyder armor & flares, and 37" Goodyear MTR/Ks.



This was my short lived 2012 on 37" MTRs in the first picture and 35" Toyos in the second:





IMO if you do something about the exhaust cross over then you won't need to mess with the driveshafts for your use. If you're really not going to take it off the highway or flex it out for more than picture taking's sake then you don't need to do anything with the driveshafts or exhaust right away. There is plenty of room there for DD duty.

I had the cross over pipe cut and replaced with a custom piece of exhaust tubing by a local exhaust shop. You can also throw some $50 Tera-Flex exhaust spacers in it and be fine.

These pictures are of a 2012 JKU with the 3.5 X-Factor installed.





Keep the stock shafts as long as you can, but if you're dead set on replacing them I've had very good luck with Tatton drivelines over the years. He stands behind his products and makes a quality shaft at an affordable price.

The Rock Krawler lifts are great whichever you start out and piece it together or go for broke right out of the box. I have been very pleased with the ride quality and handling with the many different shocks that I've run. I'd stick to Bilstein 5100s or RRDs with the two door. I think the Fox shocks are a little aggressive for a daily driver two door that doesn't have a lot of weight on it.

On your two door I would start with the 2.5 Flex or go straight for the X-Factor.

I too prefer Synergy's steering upgrades for the fine adjustments, so look at that as an option. Rock Krawler's stuff is beefy and well made, I just like to adjust things obsessively. LOL!

Happy for you, but I'm not completely wrong and will leave it at that.
