So I recently finished lifting my XJ - 3.75" up front and 4.5" in the back. I think it sits a touch too low in the front (don't mind the rake, but seems like I'm always driving downhill).

I talked to the guys out in the shop (I work for a large steel service center) and they said it would be no problem to burn a piece of plate to fit- I figure I could put 1/2" spacer between the factory isolator and the second one I just put in (I have 3" RC springs up front and a second factory isolator- they say they are 3/4" but actually measure closer to 5/8". I figure going another 1/2" would be safe - bring up the front a bit but still leave room for the rear to settle (measurements of 4.5" were done after about 60 miles of driving).

Do you see any issues with this? I would be using an epoxy glue (Gorilla Glue) to attache the steel spacer to the second isolator, just to keep it in place.

I am going to have them make me four spacers- 1/2" each just to make sure I get the ride height I want. I can always weld the two together if I want 1" more total.

4.25" front and 4.5" back should be nice.

Actual measurements are as follows with Jeep on level ground:

Front from center of axle to fender flare: 20 5/8"
Rear from center of axle to fender flare: 21 3/4"

I figure one half an inch up front will get me to 21 1/8" up front. 1/2" more will put me at 21 5/8, but that does not leave much room for rear end sag. My front bumper is probably going to bring it down some though... Not worried about the rear coming down from bumper weight, Dakota springs are tough and the above was measured with close to 100lbs of tools in the back.

What do you all think I should do?

 

BUMP for the night crowd...

I think this will work just fine, but figured I would ask in case I am missing something.

 

sorry for not posting earlier but i would lose one isolator and just make it a 3/4 inch or full one inch would work ok and probaly end up about the same all around

 

i wouldnt stack unless you have to i would stick with just one but if you weld it together it would probably be ok

 

Just pick up a couple of isolators from a junk yard. They have the correct shape and will stay centered better than plate steel (unless you machine it with the same shape as the isolator/lift spacers).

 

I have a second set of isolators- the plan is to put the steel spacer between the two sets of factory isolators- the 1/2" steel spacer will be epoxied to the second isolator. The taper on the first isolator combined with the bump stop should keep it all centered (that is the hope, anyway). I want just a bit more height than a second isolator will give me. Just wondering if anyone else thinks this will work. If I have any issues I'll just remove it and go with the two isolators I currently have.

I have RC 3" lift springs up front and 2 isolators for 3 3/4" lift. I want a touch over 4" so adding 1/2" should do it. The top edge of the factory isolator is 5/8" so the steel spacer will be held in place by the top isolator as well as expoxied to the second. The second isolator will also be held in place by 1/8" (not much) of the top isolator as well as the tapered spring top.

 

Please do not "BUMP" posts around here. If you have something new to add it's one thing, but we really frown on post "BUMPING"..

 

Well I got my spacers made. Got lucky in that I asked for 1/2"" spacers out of scrap steel next time they burn 1/2" plate- they had some to do that afternoon.
Looking at the Jeep I think I have a better way of putting them in:

Going to remove both sets of isolators, then tack weld the spacers to the top to make sure they do not shift at all. Then add the two isolators back below. I think this is a better way to do it.
We'll see how it all goes tonight when I put them in.

Should get me to 4 1/4" front and 4 3/4" in the rear.

I'll snap some pics when doing it so you can see what the heck I am talking about.
