[HELP] Modifying Rear OME lift

Hi Guys,

Jeepcommander.com and Jeepforums has been so much help with my rig.

i haave the full OME lift and i just measured it the other day and i seem to be sitting and 22.5" in the front. so i just purchased JBA strut spacers which should bring me closer to 23" and that the max i want to go with out messing anything up.

I also just purchased some JBA UCA. been paranoid after seeing a few wrecked WK XK due to the stock uca giving out.

On to my question now.

I want to level the rear to match the front. i was thinking of 2 options

1) SL rear springs. (cant seem to find them, could someone point me to where i may be able to get them) will i be able to run them with the OME shocks or do i need a longer shock? also, would i need longer rear control arms to go with that? like the ones RRO sells?

I a looking to getting a adjustable track bar in the near future.

2) add a 1/2- 1" spacer.

thanks again!

You'll want longer shocks with SL springs. You won't need longer control arms. You will want to get that adjustable track bar sooner then later. I believe the SL was on back order so getting the springs might be a little difficult. You could just add a spacer to the rear to level things out. Its a pretty cheap temporary solution until you can get what you need.

You should message a member called "gangstarr", he purchased an extra set of SL springs when he installed his, I think he just called up Superlift and ordered a set for like $100. You could also add a rear 2" lift spacer in conjunction with the OME springs, like CoreXK; I have some daystar spacers you can have for free, just pay shipping.

Either way, I ran used SL springs for a year or so before I sold the XK. There are a few things to consider, as Sal said:

1.) Longer rear shocks, I used F-150 Monroe load levelers ~$100

2.) Longer Bump stops, most use body lift pucks\extd. bolts + stock bumpstops

3.) Longer Swaybar links
Some use extd JBA quick disconnects, or don't run a swaybar at all. I first used a set of used extd SL swaybar links, but upon hitting a rut hard while off-roadin', the link was able to make contact\dent the lower control arm. I ended up runnin it with no swaybar after that, and the jeep handled just fine, with max travel all the time, this works great with the load levelers.

4.) Minor trimming of gas tank skid
Need to cut out roughly a 4"x4" section from the top of the gas tank skid to give clearance for the driver's side lower control arm. Not too hard just a tight work area, I used a handheld hacksaw.

5.) Rusty's adjustable taskbar
This really helps the driveshaft keep clear of the gas tank while flexing. Matt has a pretty straightforward install write up.

Adding rear Superlift springs put the rear an inch higher then the front, which was OME HD struts\springs + 3/8" spacer. I think the rear measurement was ~39" ground to fender with worn 265/70/17's.

Good luck sourcing and installing the springs, they definitely give the XK a ton of lift for a fraction of what the whole kit costs.

I'm also looking to run the SuperLift 4" lift springs in the rear and a modified OME spring/shock set up in the front.

I looked all over for them with no luck so far. I even started to consider the JBA 4" lift springs at $245.95, but if the SL springs could be found at about $100 I'd jump on them.

I just sent SL an email and asked if they will sell them separately from the kit along with the cost.
---------------------------------------------
Update on 3-30-15

I got a reply back today from SL that read as follows:

Thanks for your interest in our kits. For the commander we only have the 4Ē kit we sell. So I donít have a 2-2.5 lift for the rear. And to lift the rear you will need more than just the coils as you will need some drop brackets for everything to work together.

I know others have done it ...but according to SL, you can't just install a set of 4" rear springs without doing additional mods to the rear. I wonder if that's an answer for liability purposes or if they just want you to buy an entire SL 4" lift kit?
