Mixing, matching, and piecing together is what gets me looking at all the specs. There's not a single manufacturer that I like everything about their box lifts. Take a little from one, a little of another, and a few pieces from the next .

We have our engineers working on the answer to your questions and also looking at a few other things as well regarding this subject matter because we of course now what is in the pipeline for 2016. After speaking with Terry this is what he is working on. One set of rear uppers and lowers to meet all specs 1.5-3.5 Flex and X Factor Setups. This will be achieved by taking advantage of our new shanks as we require 1.5XD thread engagement always as a safety precaution. Anyway, here is what he gave us..

Front Lowers will be 22.625 - 23.25
Front Uppers will be 18.750 - 19.375
Rear Lowers will be 20.125 - 21.00
Rear Uppers will be 17.50 - 18.75

Hope that helps answer any questions... That keeps us within SAE standards for proper shank thread engagement in the arms.

That will make things a lot easier for sure.
I like the idea of shorter front uppers. The 19 1/4 now is too long especially at lower lifts.

So these are the measurements for a future set of arms and has nothing to do with your current arms?

When will these new arms be available?


What are the Min/Max specs on your current arms (Flex and X factor)?

I just read this whole thread and I can't figure out what its really about. Control arm lengths listed in instructions or frankenlifts or kids on a playground arguing over who has the most hair on their legs?

If you want to buy mix and match parts to build a custom lift then call the manufacture of what ever part(s) is in question and ask.
I have yet to run into an independent JK parts manufacture thats was not willing or able to answer compatibility related questions, they just don't like to post it on their website because its impossible to predict what parts combinations people are using. Also, These guys all know each other and can call each other(on their personal cell phone most likely) to figure out if their parts work together. (If they want to sell parts that is.)

If a manufacture blows you off when trying to shop for parts or after the sale, just go to a real off-roading event and talk to them face to face to get some answers. Hell from what I have seen I would bet most manufactures would crack open a tool box and help you fix any issue on the spot...

SLADE- Off topic and entertaining as your banter may be, you are not planning on buying any RK parts to my understanding, why not go find somewhere else to play? Possibly ProComp or Rough Countrys playground, I hear they know how long their control arms are...

Your right, I'm not going to be paying for any Rock Krawler products anytime soon (I even stated it earlier to clear any confusion). I got the same arrogance and ignorance from them when I was in the market and considering purchasing an RK lift. It's actually easier to get answers from ProComp or Rough Country on simple questions so it would not be nearly as entertaining on their playground.

I'm glad you are entertained by my simple questions to RK. What is even more entertaining is Rock Krawlers (their SALESMEN) answers or lack of which they instead provide an excuse or just ask what you drive and tell you to come wheel with them to change the subject or insinuate they are better (like some how that's going to provide the answer to the question regarding their product...). So their not out anything by not answering any question I ask and I'm not out anything by not getting an answer. Unfortunately for them, some of their future customers are more intelligent than their previous/current customers and will pick up on some of their bullshit the salesmen provide.... It's funny how Rock Krawler makes such a big deal out of not being able to provide measurements to their current product because of variations and lack of engineering approval/standards, but can instead provide measurements for arms that do not exist and are not available to their customers.... But the only thing that gets better than that is their fanboy minions praising them and complementing them for such good work on the specs to products that don't even exist. :thefinger:


So for that reason, I'll stick around and play on Rock Krawlers play ground (JKO) for my entertainment. After all, they are only a few steps away from starting their very one forum WayaRockKrawler(which I won't be a part of), that way they won't have to take any criticism, answer any hard questions, or talk about any other manufacturer......:thefinger:

So is RK saying that there are a bunch of control arms out there that are different lengths? If I'm reading this correctly the mans just asking for the lengths the arms are engineered to be at min/max. Seems pretty simple. I would hope the engineers would have a drawing with that info on it.

Our play ground is on the trails. We would love to have you join us for a run anytime. Have you posted a pic of your jeep yet?

We posted our dimensions as we state they be used. It all depends on who's rule of thumb you would like to go with as far as thread engagement is concerned as to max. lengths. We posted our conservative numbers for you. Good luck....

All you have posted is the recommended starting points.

How is it that you are capable of posting the target Minimum/Maximum length of a set of arms that are not even available BUT you can't post the Min/Max lengths for your current arms?
Your current arms along with the set of arms that "Terry... is working on" for 2016 will both share the same variations and different Rules of thumb for thread engagement....

Seems that you could just as easily post the same target measurements for your current arms as you did for your 2016 arms that are still in the works (BUT YOU WON'T).

If the Min./Max. lengths of your current arms would prove my criticism about your product wrong, I'm sure you would post up the numbers to prove me wrong and back up your product to make it look better (after all, you are salesmen). Doing so would also show your current customers along with your future customers the benefit of choosing Rock Krawler over some of the competitors that are already doing (and have been doing for a long time) what you plan to do in 2016.....

BUT you won't provide the minimum/ maximum numbers on your current arms. Pair that with the fact that "Terry" has a new set of arms in the works for 2016 that work with flex and X factor lifts from 1.5"-3.5" (like other companies already do) that address the very problem that I criticized you for....

It's safe to say that your NOT going to keep specs that help sell your product to your self and your NOT going to make another set of arms for 2016 (that would discontinue your current arms) if your current arms are covering all the bases and providing a benefit that you won't get from your competition (why do what others are doing if you have already have an edge?).


It's funny how interested you are in what I drive. Like I said before.... It's nothing special just a baby hauler... Ill give you some quick specs.

2004 TJ, 4.0, 5 speed with 36k miles on it:
37" Pitbull Rockers (Bias)
stretched to around 106" or 107" and swapped to leafs front and rear (rear SUA/ front SOA), 44044 front leafs and chevy rear leafs, around 4" or so suspension lift. additional tire clearance comes from a 1" body lift and highline tube flares.
78/79 Ford Dana 44 front I narrowed to 61" (5 lug outers), Reid knuckles, RCV shafts, Detroit locker, 5.13 gears, high steer
Ford 8.8 rear, Superior shafts/c clip eliminator, 5.13's Detroit locker
4 to 1 t case
smoothed belly with raised motor and tranny
Body armor, tube flares, and the other usual shit.

The Baby Hauler is a 2013 JK, 6 speed, Q78 TSLs, 4.88 gears, Detroit Truetrac front and rear, 2.5" coils with 8 adjustable control arms, Currie Antirocks front and rear, 1.25" BL for additional tire clearance to reduce bump stop and get full use of 11" travel shocks. Like I said, nothin special. Just my DD and Baby hauler.

Wife's Jeep Is a 2014 JKU on 35's with an auto and 3.73s, leveled (1.75" rear/ 2.75" front).


Ive had quite a few other rigs if you want to know my life history. Ive had CJ's, YJs, a TJ, JKs XJs, an M715, along with Toyotas, Samurais, and a few Full sizes.

a: He's running stock arms until RK gives in to his whining and posts min & max lengths.

b: A brand that posted lengths, because he couldn't figure it out himself.
A: I didn't bring this thread back to life. But do still find it entertaining.

B: That's pretty funny coming from you..... looking back at the measurements you were throwing around in this thread. :thefinger:


I need to do some measuring. My notes must be FUBAR.
:)
