hangar design

I SAS'd my 90 chevy a while ago using the 47" springs and ORU's kit now I'm putting 52"ers in and building a new hangar for the front.I just want to make sure this will be a strong enough design as I have never fabricated stuff before and would like to hear other opinions/options.

For attaching it to that frame I'm bolting it on using the same method as ORU.Here is their bracket that slips up onto the frame bolting on from all 3 sides.




I'm using 6" C-channel all the way across attaching both hangars and creating a new crossmember.This is how it will attach to the frame rails being bolted on from the bottom and both sides.






This is the "hangar" part of it.2 plates will slip inside the channel and the inside plate will be gusseted.

i dont know much about chevy trucks, but it looks like it should be plenty strong.

any reason that this is getting bolted together instead of welded to the frame?

plenty strong.

When most chevy guys do 52s they just move the hangar up, and have no cross to tie the mounts together and it works fine.

It will be bulletproof with the rec tubing tieing them up

Looks ok except for the retarded gussets.

ya I was upset when I found out thats the only gussets my local 4x4 shop had...ridiculous.I'll probably make my own and hide those ones inside the c-channel

I'm using all the bolts the ORU kit came with so I figured that should be plenty strong and it will be removable if I change plans in the future....no need to weld it really...

one more question.if I use 3/8" plates for all of this how do you think it will hold up as a bumper.it should only be temporary until I have enough money to build one but you never know how long that will be...

Well it will hold up really well but the frame behind it is going to hate it since whatever force the bumper/crossmember ignores will be transferred back to the sheetmetal frame rails. I would avoid hitting things, lol.

Makes sense

3/8" should be plenty for a while, lots of people do 1/4" tube, but that is overkill in my opinion (and others), anybody who does more than 1/4" has serious issues

Ya I don't know what I was thinking when I wrote that.the pictures show 3/16 and I ended up using 1/4" and meant to say that

I have it all welded up now and just need to drill holes and mount it to the frame. Now I'm just wondering how my shackle angle is gonna be. Here's what it looks like...fairly easy build. A friend suggested I could mount a winch on it it but it just seems like too much stress on it. Not to mention the lack of space between the core support and c-channel.

Just make a few sets of holes in your bottom plates for adjustability. and measure out for your shackle hangar with it in the middle hole, that way if you f up you can adjust it a little.

or just measure right the first time

Ya I measured and I'm gonna have to go as far forward as possible and my shackle angle is still gonna be too small I think...

fwiw, DIY4X has pre-drilled multi hole spring mounts. they could be welded in. this will allow adjustability.

yes I was planning on getting those but I couldn't think of a better hangar design to attach it to that would be simpler to build and as low off the frame as the ORU brackets are....
