Old Man Emu has side specific coils. So im sure the OEM coils are side specific. Theres more weight on the drivers side due to the gas tank and driver of the vehicle.

Were your OME coils side specific? Mine weren't... ordered the front from kolak and rears from JBA. Both sets were two of the same exact part number.
My OME coils for the rear were side specific. There was an A and B labeled spring (although no directions included in the box). One coil was ~1cm taller (I believe this was the A spring) and goes on the drivers side.

Interesting.
Mine were identical... no A or B on the tags, just the part numbers that are listed in ARB's application guide:

How long ago did you guys do your lifts? I wonder if they've consolidated their springs since then? I only did mine a few months ago.
I replaced mine around April of this year and ordered them from Rocky Road. I actually measured the 2 springs and the A spring is ~1cm taller.
This was from ARB when I emailed them regarding A and B springs:
Jason-
Some of the OME spring sets have “A” and “B” designations. The 2993 coils fall into this category. These designations show there is a 10mm height difference in the two springs. That difference in height is to aid you in fighting vehicle lean.
We suggest measuring your vehicle as it is now, and figuring if you have a low or high side. This info will help you find the best placement for the springs. In most applications where both front and rear springs are of the A/B style, we suggest staggering them so you do not have both taller springs on one side (front and rear), and low springs on the other.
Hope this info helps, please let us know if you have any other questions.

I wish I wasn't so OCD..... my vehicle doesn't lean so this shouldn't bother me, but I'm wondering why my springs weren't tagged A/B......
Some day when I pull out my rear springs (ie to install spacers or something) ill have to measure them to see if they're different. I did have them sitting side-by-side on my tool box and I usually notice differences like that. But who knows...
A difference in 10mm isnt really that noticable to the eye. Both of mine looked the exact same height until I measured them.

10mm = .39 inches.
That's within my "hey they're different" naked eye resolution. Lol
Edit: you must need glasses if you can't see almost 1/2" difference in parts.
