Factory Five lists three part numbers for the Koni coil overs.
#14676 front
#14675 rear solid axle
#15995 IRS rear
Are there any differences in the shocks or is it just the springs that make up the different part numbers?
The shocks I received (red Koni) are all the same exact part.

I just lunpacked my shock and installed the fronts this weekend. I have the IRS, and the 4 shocks and all components are identical, except the front springs are 500lb and the rears are 400lb. That is the only difference.

I got the answer from Dan at FF that for IRS the fronts and rears are the same. soldi axle is different as called out in the manual
Well, I stand corrected. After seeing the reply by @mmklaxer, I went back and reviewed my inventory sheets and there is a different part number for the front vs. rear for the solid axle.

Well, now we got some questions to all these answers! So looks like all have the same size springs, just different rates. Now what's the diff between 30-1720 and 21. And is there a different 30-17 number on the IRS?
It looks like the part numbers represent different extended lengths according to this:
