You can get by without it at 3 inches. Any higher and you gotta get a sye/cvds/brake lines/etc.....



But, as with any lift, changing the suspension geometry is advised.

 

thanks dude

 

You do not have to have a SYE.
I am at 4 without one. If i got vibrations i would get a tcase drop which is really cheap.

 

Hey guys, sorry for the terrible question.

I have some 235's on my XJ, and the 15" steel rims.

Now, the manual says that tires should be inflated to 33psi? Something like that.

However on the tire it says up to 52psi I think.

The tires sag at the bottom which is why I think I should inflate more. Right now they are at 39psi.

What psi should I be using?

 

Depends on the year actually. On older models (pre '97), you can often run up to 4" or so without needing an SYE. But on '97 and newer, you can start getting vibes as low as 3". Mine is a '99 and I had vibes at 3".


That's a little high if you ask me. I run 28-30 in my 33's for a little softer ride. Takes an MPG or two away from me at the pump, but I'm okay with that. On 235's you should be fine around 33-35 for normal highway driving. A little bit of bulge at the bottom is normal.

 

I run anywhere between 20 and 30. When i am wheeling i go all day at 20. With rocks and hard wheeling i go to 15. But i never go on the highway below 20. I run between 28 and 30 for daily driving.

 

on my old 235s i ran at 35, on my 32s i run at 40. the sag at the bottom could be if your wheels are turned, if you're on a hill, etc.

 

So how much (approximate, I assume; condition, age, etc.) lift will V8 ZJ coils and an S10 bastard pack give me?

Oh, and will 31"s rub on a 3" lift, without trimming?

 

Hello all. A while back I found a wrecked 90 with an unknown lift at the junkyard. Yesterday I installed the rear springs which consist of an add-a leaf, with a much better spring pac than my old worn out negitive arched leaves. Gave me right about 4". the rubber brake line hooked back up, but I will be replacing it ASAP because it looked like much axel travel and it could pull apart. Today I am going to install the front kit which consists of coils and 2" plastic spacers. I am guessing that this is a 3" lift kit more or less. I would have also bought various front suspension / steering parts but, the donor cherokee looked like it had hit a utility pole. The big question is, aside from probably needing longer brake hose, will I be needing to move the track bar or any other front end parts? How about transfer case drop? I'm hoping to not have to mess with it. I will post my progress later today. Here is a "pre-lift" picture. Worn out stock springs with 31" Super Swampers. I'm gonna go start on the front now. I will be checking in every time I take a coffee break. Thanks, zim

 

Yeah you're gonna want to relocate the track bar. You shouldn't need a t-case drop at 3", because it's a '90 and it has the longer output housing.

 

My lift comes in soon, what bolts should I start hitting with PB?

 

Hey thanks. What do you recommend..3/4"? 1" relocate?
Zim is out tearin it down right now...this is mrs. zim

 

When I did mine we had a hard time with the control arms and everything having to do with the rear springs...especially at the shackle

 

A few hours later and my 90 is setting up where she needs to be. Took the fender flares off and still need to trim the front. Ended up only using the 2" poly spacer in the front. That leaves me a bit high in the rear, but it allowed me to leave the track bar alone. Other than new shocks all around, and a longer rear brake line. I think I'm good to go. Here's the almost finished look.

 

i just did my lift. i used castle penetrating oil instead of pb blaster. i sprayed the control arms, upper rear shock bolts, rear shackles, rear brakeline nuts, inside the pockets of where the leafs mount in the rocker, steering stabilizer bolt, old u-bolts on rear leafs, steering linkage, etc. i dont know why im attempting to list everything, but i did spray pretty much everything. anything that is rusty and you think needs to be sprayed, spray it.
