Post subject:  Fabtech Dirt logic coil-overs
Just got a reply from Fabtech.

They said that they should be releaseing their Dirt Logic 2.5 adjustable coil-overs for the KJ some time around the first of the year. They recently released them for the WK, and are working on fittment for the KJ.

:D :D :D :D

If Fabtech were smart, which i'm sure they are, they'll produce a coilover kit with ride height adjustable platforms/sleeves. This way we can 'tune' the height of our KJ's as the accessories start to flow :P!!

Their kit would have to include a new clevis to mount the coilover onto. Should look pretty wild. I hope they dont go overboard with the suspension downwards travel as the angle of the CV and R&P steering wont like it. :(

Here's the WK system -

It's adapted to the stock clevis and has a billet top mount. On the WK, it provides 3" of lift. Looks like the ride height is adjustable.

Biggest advantages I see are:
Coil selection. Coils for coilover shocks are available in MANY lengths and MANY rates. Allowing easy tuning for bumpers, winches, and us crd guys. The coils are also pretty cheap, $60-$90 each. Many mfg's to choose from, I ussually use QA1 as they are reasonable and the quality is good.
Height adjustment. With the threaded body and collars you can easily make ride height adjustments. I would suspect at least 2" of adjustment on these shocks in our application.
Valve adjustability. The valving on this style of shock is adjustable. Not too difficult to do at home, but also fairly cheap to send in and have tweaked.
Charge adjustability. You can experiment with the amount of gas charge in the shock to tweak the ride characteristics to you liking. Any motorcycle or offroad shop should have a nitrogen bottle and regulator for this purpose. Ussually a very minimal charge.
Rebuildable. All the major parts and seal are replaceable and rebuildable. No need to EVER have to replace them.

Basically you can tune a shock like this to fit you needs exactly and if you add a bumper/winch later, you can tune them to ride and work just like before....for not too much more $$

I love coil overs, not only for the tune-ability, but you will also be amazed at the difference in the quality of the dampening they provide. I ran Ranchos, KYB's, and DT's on my Bronco beofre I went to Fox's. I was amazed at the improvement.

I am VERY excited for these....It is sure to bring others to the market as well!

Wish they would make a unit for the rear too. Get rid of the spring and shock and have an adjustable coil over.

Im not real familiar with this whole coil over thing. Looks like the spring covers up the shock hence the name I guess, whereas on a strut the spring does not go over the shock absorber section of the strut? Help me out here. Looks like for the same ride height you have a longer spring with the coil over, which to me says that we could possibly get more wheel travel out of this setup, along with the adjustability that was mentioned.

Edit: Okay someone just tell me what is the big difference between a coil over and a strut where the KJ is concerned.

My upper control arm makes contact with the springs now. I took the front wheels off this weekend to pound down the pinch weld and there was definite contact (previous set of control arms were worn down where the ball joints contacted the spring, too).

Would this coilover kit from fabtech address this kind of issue?

That's what I asked earlier and no replies.

Basically you said it....Struts in the case ofKJ's are essentially a non adjustable coilover....Symantics really.
However, in many applications struts serve a bigger purpose than just shock and spring. The actually serve as a locating device for the suspension, a sort of upper control arm.
It is likely the coil will be longer, as you said. As well as the rebuild ability/adjustability I mention is really all that sets them apart.
Basically in our case the strut is a OEM coil over....

Excellent post milner.

The other big advantage to the coilover vs our struts is that the overall diameter will be smaller with the coilover...which will put the upper control arm farther away from the coilover.

Also since it has the "adjustable sleeve" you can adjust the ride height with about 10 minutes of work. Say you run 245/70/16s...you could run near stock height on the street...better stability, better mpg, ect.

When you go offroad, you just need to release the weight off a wheel and then you can turn the collar on the threaded sleeve until you have 1-2-2.5 inches of lift. The only issue would be alingment. If you can get zero bump steer (with adjustable sway bar links or something) then when you lift you won't throw your toe out of adjustment. Otherwise set your alingment for street and the "toe in/out" won't be that big of an issue offroad.

The sleeve also lets you adjust for springs that sag...different equipment like front bumpers or a winch, If wwe could get rear coilovers you could also adjust for load and towing.

UBJ problems would be nice to avoid, I like to learn stuff, thanks for all the good info, keep it coming! Oh, and as far as limiting the droop, I say let it drop, put a limiting strap on it till we find a way to let it drop without breaking stuff :shock:

Post subject:  doesn't sound like these are going to happen
i just got off the phone with fab tech. spoke with josh. he asked a ton of people there - and they all said the front coil over set up was discussed for the liberties but the project was cancelled. major bummer! if someone knows something other than what josh at fab tech shared with me - please let me know!! i sent him the link to this thread - as well as the link to the lost kjs forum. i shared with him the demand for an adjustable front coil over set up for the liberties would be huge!! he said he'd bring it up at his next meeting.

we'll see what happens. for now - i'm not holding my breath.

bummer.

Post subject:  one more thing...
maybe it would help if folks called fab tech to express their interest in an adjustable front coil over? their number is 877-432-2832. they are in the business to make money. if they know there is a market ready and waiing to purchase their products - they may be more willing to put something together for us?

if you're interested - pick up the phone and say so!!

i for one would love a set of these!! it would solve so many of the front end lift problems we are currently having and allow us to get away from pucks, OTT spacers, sagging, dilemas over extra weight from diesel engines, bull bumpers, winches, and leveling out our rigs!!

Why in the H*LL would they send me an e-mail saying that they were working on it if they cancelled it. :evil:

I think some of these suspension companies need to pull their heads out of their a** & stop saying they're going to do something when they're not. :evil:

I will definatly be contacting them about the misinformation they sent me.

Feck yeah!! I really hope they make these things, I reckon they'd sell out of production, of course, if they were reasonably priced :P!
