I second that!
Shopping for a 1" spacer for the rear myself.. don't like stacking isolators, and don't want the hassle of cutting down 1.5" poly if I don't have to.

I think it should work just fine. I installed the WJ front upper coil spring isolators on the top of my XK rear springs and they fit great. I gained around 5/8" in the rear after it had a week or so to settle.

The isolators were cheap and in stock locally so I didn't have to order any parts to do this. I might still pull it back apart and use a 3/4" or 1" WJ spacer along w/the stock WK/XK isolator when I get some time though.

Here are exact specs from Rough Country. The WJ spacers will have about an 1/8" of clearance all the way around the inner ring. I noticed that the WJ isolators I used are a hair looser than the stock ones but barely noticeable and they don't move once you get some weight on them. I'm sure you could shim these pretty easily too if you're really worried about the gap.

Ok, so i finally went to install the pro comp 1" wj front spacers in the rear of my wk. The inside diameter is too small to fit over the alignment cup on the top of the spring perch, and theres no way to fasten them to the bottom spring perch. I had 2" poly spacers from terafex and just put those on, as well as installed new bilstein 5100's. I put the front struts on the tallest setting, but now its just a bit too tall in the front. :brickwall One of the reasons I started this over ambitious project was to replace the stupid worn out front diff upper bushing. I bailed on that too. So now im hoping the front struts settle some, otherwise its back to my buddy's shop to drop the Bilsteins down a notch and get some slight rake back. Im so sick of working on this jeep, and i still havent fixed the diff bushing issue either.

I ended up using the Rough Country WJ .75" upper coil spacers on top of the rear coils. As I thought, they were just a hair loose around the bump stop mounting post but they haven't budged since installing.

Not sure why those Pro Comp ones wouldn't work though. Are you sure they were for a WJ front upper coil?

Either way, Those Bilstein 5100 struts give you .75" of lift on their lowest setting. Most people w/ modified OME lifts are running those at that setting w/the MD coils unless they have a front bumper. If you're over 23" from hub to fender in the front you way want to get those lowered soon b/c over that height the CV axles are pretty stretched and you'll probably start doing damage to them before too long.
