Looking for a good rear spring perch relocation write-ups

[Vinman]

I know I saw a very detailed write-up about how to relocate the rear upper spring perches to compensate for rotating the pinion up.
I’ve spent the last half hour looking but haven’t come up with a detailed post, anybody know of any?

There is a hole at the top of the frame arch. Match that up with the center hole in the factory spring seat. That's all there is to it.

Well I’ll be damn, that was easy. Thanks dude

 

[Vinman]

And all finished

That was fast

Very!

Very nice work, that was fast!

As a hypothetical, if I were to use aftermarket spring perch's, would the same principle still apply? I'm assuming that the little "hole" is were the bump stop bolt threads in, so it would be the center of the spring and I would line that up with the hole at the top of the spring arch just like the OP did?

That's some shiny paint!

Depends on which spring perches you use.

I used these ones:

I like them because once you install the top perch bracket to the frame, you have 5 different holes you can use to reposition the spring perch to your liking.

Not that you'd probably ever need to move it around, but I suppose if you changed lift heights or something, it could be handy.

There is no reason to use aftermarket anything for this.

Lol, those pics were taken about 3 seconds after I painted it. It’s satin black once dry.

I'm confused about what purpose the square bits serve? I was looking at the Rokmen ones, but...

So as long as I'm extra careful when removing the factory ones, I should just re weld them back on? Are new one's really a big waste?

Look at the photos. The square bit is the bracket, the circular piece is the spring perch.

In hindsight, I could have just used the stock perches and relocated them. In my mind I was just worried somehow I would end up messing them up in the process of cutting them off, hence the reason I bought the GenRight ones.

It's easier to just reuse the stock ones, unless yours are rusted out, at which point something like this works just fine.

no they aren't rusted, I was just thinking along the same lines in that I was assuming I wouldn't be able to remove them cleanly. But I'll give this a shot first!

Yeah, I was overthinking it.

You should be able to remove them cleanly with the right cutting tools.

Either way, the GenRight ones ended up going on my TJ. They are adjustable, but I guess that really doesn't serve a purpose unless you're going up (or down) in lift height. Or maybe you just want some extra height in the rear to handle a lot of extra weight?

Weld the old ones back on. New ones are a waste exactly in the amount you paid for them.

There is no adjusting. Regardless of the lift height, the spring seats go in the same place. 3,4,5" of lift, they go in the same spot.

Taken right from the GenRight product page:

"This simple design is also adjustable forward or backward 1" once welded in place."

So they are just making that up? You can adjust it, clearly. What for, I'm not sure, but it's obvious they're adjustable.

Maybe adjust positioning for a small change in wheelbase?

That was my thought as well.
