I was looking at 1.75" coil spacers and 1.5" shackles should I get this or should I go with the Teraflex 2" Budget boost. I really want to fit 31" tires without having to change shocks.

 

They're about the same. You will be able to fit 31s no sweat!! No need for extended brake lines either. If you take the rear anti sway bar off and throw it as far as you can, and buy a set of discos for the front, that XJ will shock you with the amount of flex you get out of it. Disconnect the ASBs and test out the flex with someone watching to see if you need to reroute the hard lines, but that's is all you should have to do as as far as BLs are concerned. HTH!! Later!!

 

So will the Teraflex 2" Budget boost get me to 4" or 3" to 3.5"?

 

Depends on what you have now. OME tends to give 1.5 - 2" of lift. How much do you have now? I got 2" front and about 1.5" in the rear before i added additional lift.

 

As COS said, you dont need front brake lines. Just straighten out the bend in the hard line on unirail.

You also dont need BPE's. Most dont work with OME shocks anyway.

Measure the distance between the the lower lip of your fender flare and the center of your wheel/axleshaft. Rear was 17.5" and front was 17" when it rolled off the assembly line. Deduct above measurements from your actual measurement for your lift total. Do this on level ground.

 

He will need a longer rear brake line though. That's only about $20 at the parts store, maybe less.

 

YJ lines are the ones to use in front unless you are going real tall. The Dodge Dakota rear line works great.

 

I use a YJ line in the rear. It's 3" longer than stock and works well with my 3" lift. The stock line was pretty stretched so i had no choice but to swap it out.

 

Yeah YJ lines work either front or rearon lifts up to 4.5". The Dakota rear also works and is 5" longer than OEM ones IIRC. So at a taller height the YJ rear line may be too short.
BTW the right side rear E-Brake line will lengthen the short E-Bake cables but you have to use the right sided YJ one to replace both XJ ones. (Right side YJ is longer than Left.)

 

Good and useful info there

 

I have 2" of lift

 

I have 2" of lift so what will this bring me out to after the lift?

 

Well if you have 2" now, you will have 4" up front and maybe 3.5" in the rear. At this height you may need additional components.

To give you an idea, here's what i have or had:

2" ome kit
2" front spacers
OME AAL (1.5")
OME 2" shocks with modified Full Traction BPE's
JKS adjustable front trackbar
eye-to-eye sway bar link conversion kit from Warrior Products (2" longer than stock)
Rear YJ brake line (3" longer than stock)
PORC sye kit and front xj driveshaft for rear.

I had serious vibrations with the OME kit alone, and it only got worse when i went to 4" so i had to get the sye kit or drop the transfer case.

 

What if I got the Daystar 1 3/4" front coil spacers and 1" shackles would I still be able to fit 31's without rubbing or should I get 1.5" shackles?

 

Focus more on the front. That's where all the rubbing takes place in most cases. You can easily stop rubbing in the rear by increasing your bumpstop length back there but you still want to keep the jeep even with the front. What you want to do is get the front clear of any rubbing and then lift the rear to match the front's height.

What i would suggest you do is if you get new 31" tires, do it first and then lift to clear them. That way you know what needs to be done and not have to guess as we are doing now. You will still be able to drive it while you wait for parts but it will rub a little when turning.

The problem with 3.75" backspacing and 31" tires is that when you turn, the tires start rubbing on the lowest part of the front bumper and lowest part of the rear fender, right at the corner. This is prevented by cutting, trimming, or lifting it more. I trimmed mine a little so it's not noticeable. If you want pictures of what i did, i can get you some.
