Rear bags in but hanging up when aired out

So this weekend, I was able to put in the bolt in c-notch, 2" lowering blocks and my 2600 dom's in the rear (no air supply just yet, so it's sitting at full dump). When I put it down, the nose of the pumpkin (in-between the u joints and the axel tubes) hits the shock x-mbr before the axel goes all the way up into the c-notch. If this wouldn't happen, I could probably go down another inch or so.

I've read A LOT posts about this type of install, and I don't recall this ever being an issue. My question is, is it ok to just cut a section out of the xmbr where the nose is hitting it?

I know, the pictures are horrible, but I finished this up late last night so it's all I got...

Re: Rear bags in but hanging up when aired out

I wish I did but I didn't think of it while it was up in the air...but I'm hoping to get back on it tonight and I'll get a pic of where it's hitting for some opinions. I hope my phone takes better pics than the last ones since that's all I have for digital pics right now.

put a shop light under your truck for extra light if using a cell phone without a flash.

Will do...I stole this pic from the "Make it handle" thread and squared off the cross member I'm talking about. I'll still get an actual pic hopefully tonight...

Re: Rear bags in but hanging up when aired out

I looked at mine last night and that piece is not modified. what does your pinion angle look like? does it look like this ^ ?

Re: Rear bags in but hanging up when aired out

Worked on the blazer this weekend a little more...man it's been slow moving...I took a closer look at this issue, and the top of the pumpkin is also hitting the floor board, so if I do anything about it, I'll have to cut that as well.

Anyways, I didn't take any pictures of my own, but I found this one by tcb-1 and it looks like he had the same exact issue. If I do this releif cut, I'll gain about 1/2" more drop on each side...actually more on the passenger since it sits a little crooked right now, I'm guessing since the pumpkin is offset and there's more weight on the driver side making it lower.

Just thought I'd post this so no one thinks I'm crazy

PS, my pinion angle was only about 2 degrees off of the tranny's.

Re: Rear bags in but hanging up when aired out

the diff hits the floorboards on my blazer too. Yours must sit a little higher because of the overall tire height. Do you plan on raising any part of the floor?

Re: Rear bags in but hanging up when aired out

Nah...I know it's ghetto, but if I end up cutting the xmbr, I'll just cut a hole in the floor for the pumpkin too. It's right under the seat and covered by carpet so no one will ever see it. I was thinking about loosely covering the hole with some dynomat just so fumes, water, whatever doesn't come up through the hole.

Before I do any of that I want to finish the front to see how it sits aired out on all 4 corners. I want to make sure the back doesn't sit lower than the front.

I have the front all prepped and ready to install the bags, but put the springs back in so I can pull it in and out of the garage as needed. I didn't even set it on the ground with the fronts on...just ran out of time. I didn't leave the bags in because I'm still gathering parts to finish up the york edc and I need to be able to get the jack under it...it's a PITA right now with the rear aired out and no way to lift it.
