JK with Nth Degree 4" lift

[haven]

Here's a couple of photos of a JK with 4" lift
from Nth Degree, with 35" tall tires. 35 is all
that will fit due to the extreme articulation
this suspension makes possible.

nice rig, there is one here in memphis (2-dr though) that is running a 4" lift with 37s tucked underneath it, very nice looking rig....i'll have to find a pic of it to share

Wow, that really is an awesome rig! Those JKs make me...:drool:

[crawler#976]

That looks great! If I didn't already have three Toy's I'd consider it.

Micheal is in Moab this week putting that Jeep through its paces. :punk03: He said that is rides CONSIDERABLY better on the street with the Nth Degree suspension.

You have remarkable self control. I would have added an inch of bumpstop to run 37's.

Why 37's, do you think the larger tires would really be beneficial for the extra stress that is put on the other components. Woundn't mind some thoughts sense I am first on the list for this Nth degree kit when it hits the public. I guess I am also asking because I went with 33's on my 03 Rubicon and then about a year later switched to 35's. I really don't want to make this mistake twice. Anyone, thoughts!

I think it really just depends on what you plan to use the vehicle for. I'm still running the stock 30s (or 31s) on my '05 Rubicon and I've been able to do everything that I've wanted to do thus far including some pretty sick stuff up in Colorado near Great Sand Dunes. If you want to do hardcore rock crawling, then the larger tires and lift will provide the clearance you need. However, if you're more interested in enjoying backcountry trails, with moderate obstacles, and more vehicle-dependent travel, I wouldn't suggest going up to 37s. One thing to keep in mind is that once you spend the money on lifts/tire size increases, you'll keep spending and spending and spending...

Good luck either way, hope this helps!

my understanding of nth kits (and most kits in general) is the weak link is the bushings.

they had probs w/ the bushing getting worn/sloppy w/ the orig TJ kit.

not sure if they addressed it (there was talk of an aviation type stainless mesh bushing, not sure how seriously considered though) in the JK.

That is the first time I have heard that. Have you seen their bushings? They are different than anything else on the market, they have a ball and socket design with different durometer bushings on the front and rear. You can easily change out the bushing for different durometers if the wear is too high.

The JK owner of this rig owns a shop up in Big Bear that specializes in Nth Degree kits. They are also a big supporter of the Jeep Liberty (KJ) crowd.

I believe this is a Nth degree kit on their rig, but not 100% on that. Heather and Quinn at All J products. www.boulderbars.com

yeah, when i first saw the kit i thought that it solved many of the probs w/ standard donut bushings or heim type joints re wear.
however talking to installers at last yrs offroad expo in pomona, they said that there were probs w/ the bushings and that nth was adressing them.
not sure if mult durometers was the fix. i hope they got it fixed as their kit seemed to be a good design.
bushings have been the weak link in RE/FullTraction/Fabtech/etc. never understood why they could not get them to last as long as OEM rubber.
maybe they finally found a good source.
i am about 1.5 yrs out of the jeep research (so my comments are dated) but thinking bout the JK if they put a hemi in it.

It's all about that "envy" factor. I know somebody on 35's that went to 36's, then met another on 36's that went up to 37's. 33" guys are always looking to squeeze in 35's, and we poor saps on 31's are looking for anything!

There will always be some obstacle somewhere that'll make you say, "if I only had another inch of clearance!"

35's seem to wear well on the body of those. and with all that wheelbase, it seems like a bigger tire is justified to help out the breakover.

JKs with 35"s are way to sporty especially the green ones you had better give it here!:sport_box

The issues are simple in that the original design of the suspension is an over-constrained 5 link design. What many people do not understand is that the bushings ARE a part of the overall spring rate of this suspension design, as the panhard rod over-constrains the axle and the only method of movement is through the compression of the bushings. When you lift a vehicle suck as TJ or JK, you place even greater stress on all the rubber bushings in the system, due again, to the changes in the axle position.

If you were to have infinitely stiff control arms and panhard rod, replace the rubber bushings with rigid u-joints having 2 degrees of freedom, and tried to cycle the suspension, you would find that it would only move towards jounce or rebound, to the extent of the assembly clearance between bolts and mating components (the "slop" in the joints).

This can all be corrected, but the correction effort is neither quick, nor cheap.

I'm running a 6" Nth LA system on my LJ, I have not had any of these issues that you are talking about. I have close to 15,000 miles on the system with several really rough days on the rocks. It rides smooth as silk on the Pavement and is amazing off road. The only trouble I have run into so far is the Swaybar links that came with the kit kept popping out usually in the middle of an exit ramp or something. I remedied it by installing an ORO swayloc. There is definately cheaper ways to fix the problem but the ORO swaybar works really well.

As long as you keep everything greased it's fine.
