Standard Jeep Coil Spring OD?

[fl0w3n]

Newb question I'm confused on...

I want to use these Ruff Stuff coil mount brackets, and they come in a 4", 4.5", and 5.5" size depending on COIL OD according to them.

Measuring a loose coil I have from my XJ, I show the OD (like Ruff Stuff says) as closer to 5.25" and the ID is 4". It doesn't make sense to me that a Jeep would be on the bigger side of the OD range of what's available, so the 5.5" doesn't seem right.

I called Ruff Stuff and they seemed kinda unsure of which one I should go with.

Has anyone used these coil brackets and know what will fit a Jeep coil?

Idk how helpful this is for comparison, but, since I have a ton of different spring stuff already off the jeep and easy to measure:

The Artec “ultimate XJ spring brackets” (pictured in gloss black, welded onto your WJ axle) the ID measures 4”.

My OEM XJ D30 brackets, the “cap” measures 3.5” diameter, but it bulges out underneath it, to about 4”.

Then I have these JK spring perches, that I found on sale for $32, too good to pass up, and I can use them on my 4-link project, and they are 3.75” diameter. I think Rubicon Express is just blowing them out, on other sites they are $200+

Amazon.com

And then I don’t have any OEM XJ springs to measure, but the outer diameter of both my Skyjacker and Rubicon Express coils are both 5.5” exactly.

I am almost certain that the 5.5” ones would be the ones you want, I can’t see any way that you’d get the smaller ones to work, unless you were using some “non-standard” springs (like 3.5” coilover springs with no shock?)
