LJ Build Problems

I own a 2006 LJ that's been running a 2.5" Rancho Rock Krawler suspension kit and a 1" MML and 1.25" BL. I also have a SYE and CV drive shaft but at this point in my build I have decided I want a bit more clearance to fit a set of 35s under my Jeep. I also have a set of RE adjustable upper control arms from Rough country ready to be installed to adjust my pinion angle.

Now I have done some research and found that a guy who has the same lift kit also wanted a bit more ride height and so he swapped out his spring for Rancho's slightly taller 3.5" lift springs and claims it has put him closer to the 4" he wanted while apparently not adjusting the the rest of the equipment. My concern performing something like this worth the effort? Or is it better to put money in for a new 4" lift kit? Would I see problems with my sway bar disconnects restricting my ride height? would my shocks be stretched out to be longer than I would want? Any other issues I may see with just swapping springs? What I wanted to do is put a 4" set of springs in form my 2.5" springs that I am currently running.

If I were to save up for a different lift kit, has anyone had experience with the Rough Country 4" short arm or long arm kits? these are what I am leaning toward if I replace my current kit.

Rough country is probably the lowest quality kit on the market.

Ok well that not exactly what I am trying to get at. My major concern is can I easily go from my Rancho shocks from a 2.5" suspension kit to a set of 4" springs such as the 4" Old Man Emu fronts and rears

oh...where to start....

Let's start with this - do you want to "fit" 35s? or you want to actually "run" 35s? they are very different things. "fitting" looks good for pictures while sitting in your driveway, but isn't functional and doesn't "work". If you want them to be functional & "work", you'll need quite a bit of work.

you bought Rubicon Express parts from Rough Country?

sounds like his stuff is pretty messed up. i wouldn't listen to him. keep in mind sometimes free advice is worth less than you paid for it.

A "kit" is nothing more than a collection of components.

You need to have a specific collection of components if you want your stuff to work, regardless of height. It's your job to figure out what components you need and why. Buy parts based on component requirements, not based on "kit". if you find a "kit" that includes enough to get you part of the way there, good deal. But keep in mind at the 4" lift height level with 35s, a ~70% complete kit is generally in the $2k neighborhood.

the question is phrased completely wrong, but i think I know what you're getting at....yes you will need to address sway bar links with a height change.

again...yes shocks will need changed. along with a bunch of other stuff.

then you'll need everything you don't have now that would be required to go to 4" of lift.

no you can't just slap 4" spring in there and assume everything else is fine. can pretty much guarantee it wont' be.

The shocks are Rancho RS5000 with what I believe to have 26.38" extended and 15.75" compressed. The shocks are the same in the back and front.

Ok let's start from the beginning. I would like to run 35s in the next year. I basically want to be able to tuck them up cleanly under my fenders as well as get decent extension.

I apologize, I didnt mean RE i just meant rear uppers.

Now I can see what you mean with things sounding pretty messed up. But I have also found an interesting article about coil spacers vs new springs that sparked my interest and getting a little more ride height. Here is the article:

Coil Spacers Vs. New Springs - The Need-To-Knows Before You Lift

Where would I see issues with swapping in slightly taller coils?

They should be long enough.

Shock lengths, bumpstop extension lengths, sway bar lengths, brake line lengths, alignment (caster & toe), axle position, track bars, etc. Stacking spacers on top of lift springs will add coil binding & damage to that list of potential problems.

Even 33s on the LJ need a brake upgrade, IMHO. the LJ's brakes suck worse than they do on TJ's for some reason, maybe it's the extra weight. For 35s you'll definitely need a Vanco Big Brake kit. I run their 15" kit with 33s, and the Jeep finally stops like it should have from the factory. Even with only 31s it was downright scary at times...actually got in an accident because the stock brake design sucks so bad.

do tell how that 4" lift + TT + SWB + axle position/pinion angle thing worked out?

It'll be good for the OP to understand what he's getting himself into

But the difference is that a SWB TJ IS worth the trouble








Ok OP, sorry to derail a thread but I couldn't resist!

Hey Phillips57 other than the ride height were you pleased with the Rancho kit? I've been thinking about going with the Rancho kit for my '05 LJ.

I really enjoy the Rancho kit. I had it install a while back and it runs great I am just ready to move up to something a bit bigger so I can run some larger tires. It comes with everything you need. The only thing I did not like was the transfer case skid plate drop so I got a 1"MML and a 1.25" BL to regain some clearance under my jeep. It's a lot of fun to get the sway bar disconnects out and wheel around. You'll get some great articulation. Hope this helps Lawless. Also if you need any of the pieces. I have some of a second set laying around unused because I had been in a bad rear collision accident. Springs, brake lines, Pitman arm.

I think hosejockey61 is just jealous.

And I'm just mentioning that I have a few extra parts laying around from one of the two lift kits I have. I have the full kit on my jeep but then have half of another one of the kits just laying around as back up parts. I had parts replaced after a bad accident.
