Rear upper spring perch

[tworley]

Currie bumpstops. I removed the previous bumpstop extension and the bolt was stripped/corroded which damaged the threads on the upper spring perch. I ran a tap thru it, but the currie M10-1.5x~2.5 bolt has a lot of wiggle. Should I
1) Tap next size bigger or
2) get 3 or 3.5" M10-1.5x bolt and just install a nut/washer/loctite on the top of the perch?

Thoughts?

Is there enough meat there to drill and use a threaded insert so your bolt size stays the same?

I've got those on order. And I need to cut off my perches and relocate. Makes me wonder if I shouldn't order something beefier.

I'd probably weld some 1/4" or 3/8" plate in there and drill and tap.

The perch I believe is 3/16" thick, not sure if that is enough or not...

Option 2 seems easiest to me. If you have a welder I’d put some healthy tacks on the washer and nut so you don’t need to worry about holding it to remove.

Use the OE perch, they're easy to relocate. The bumps don't see anything extreme, I don't think 1/4" or 3/8" is warranted there.

Also an option that crossed my mind.

Much easier to do the job, yes.

I've got a pair that I cut off my frame that are in good shape if any of you need them.

You don't have to

 

[jjvw]

...,do you have to remove the tank?

I did not. But it is easier if you do.

I think the easiest thing to do is tap to the next larger size.

One thing to check would be if the mount and jounce will play nice with a larger bolt. A second thing to check is how bothered you are to have mismatched bolts side to side and have to refigure that out each time they get disassembled.

I was thinking to do both sides, if the larger bolt will fit, because I’m anal and must have both sides matching.

I can tell you this after reinstalling my driver's rear spring five times on The Rubicon do whatever you can do to make trail repairs easy and intuitive.

No judgement if you are into that.

I really need to do this,tired of the bent spring,will it change my ride height,thanks guys.

...,will it change my ride height,thanks guys.

Depends on how you do it. When I moved mine, I trimmed away as much as I could to fit the disc up into the arch. I lost a bit of ride height with the intention of using various thin spacers to adjust the height. Which I have multiple times over the years as things evolved.

Yes,I have used street rays (eBay spacers )with good results .
