8.8 axle swap issues

I was working on my 8.8 swap Friday, set myself up to start locating my brackets and noticed my brackets weren't fitting the best. I purchased my bracket kit from Iron Rock off road, anyone else dealt with these guys? I had to massage the sway bar mounts, they were leaning about 5° in the same direction. The shock mounts went on great, no hassles. When i tried to assemble the spring mounts they would not go together, the tabs that fit into the slots was WAY oversize, 1.00" long vs. .500" long slot in the spring plate. I milled them down to fit in the slots, but it still doesn't work. They fit into the plate now, but it doesn't fit the 3.25" dia of the 8.8 axle, it is more like 3" dia that allows the tabs to seat correctly. I have called and emailed I.R.O.R. with my concerns, but have yet to reach anyone. Needless to say, I was pissed off Friday, I was going to be finished up and ready to take it to my friend, the Ford mechanic, to have the gears swapped out for 4.56's. Now I am stuck, waiting on feedback from I.R.O.R.

Here is a pic of my "stopping point"

damn bro that sucks, im in the middle of a HPD30/8.8 swap myself and planned on ordering these aswell,maybe not now. If you return those check out M.O.R.E offroad.

Sources for better quality conversion brackets are from either M.O.R.E. or Rubicon Express.

I just received feedback from I.R.O.R., they did send me some wrong parts. They are sending out some new parts today, so I guess I can't slam them too bad. At least they are going to make it right, it could have been an even bigger mess. I do prefer their shock mounts over M.O.R.E.'s design, it doesn't hold the shock attachment point in double shear, but it allows for minimal binding as the suspension flexes, and all the brackets are 3/16" or 1/4" thick.

Is there a link that shows a pic of IROR's shock mount? Just curious what it looks like, I can't picture a single-shear shock mount which might be something cool. Hmmm, after thinking about it, is that the kind that has a stud protruding out with a single nut holding the bottom shock mount? That's what I have on my rear axle with outboarded shocks.

It is very similar to that, I'm pretty sure it uses a longer bolt to fasten the shock. Unless you weld in a stud yourself, it is just a bracket with a hole. As soon as I get my new parts and go back up to the shop to put them on, I'll shoot some pics and post them. The shock brackets they sent me do not match the picture on their website, but it matches the picture in the instructions provided, didn't catch that until now! If you look at the picture on their website it shows the track bar & spring perch brackets pre-welded, but when you open the box they are not....... "some assembly required"..... LOL

This is a photo from Stu Olson's website that shows what my rear shock mount looks like, the shock is in single shear.

Less the bad weld job holding the bracket to the axle tube that is.

Very similar Jerry, except it welds directly to the axle tube instead of piggy back. I tried to post the instruction manual which shows it and how it mounts very clearly, but it is a word document and I guess i'll have to figure out how to convert it to PDF format, unless you want me to email it to you or anybody else for that matter.

I managed to convert a picture from their manual showing placement of the shock brackets.

Gotcha, I see it now. Thanks for posting that pic.

The reason mine is piggybacked onto the control arm bracket is that it moves the lower shock mount a few inches outboard which really makes for a nice improvement in handling. My '97 TJ (stolen in March) did not have the rear shocks like that but the '04 TJ I bought from a fabricator friend came that way and the better handling is pretty dramatic. I should have done that to my '97.

That makes sense, I may slide mine out after I do some measuring. I will probably need some longer shocks though, and actually I'm ready for them now, those RC 2.2's are pretty stiff.
