Tbone,
Will the IRO's shorten your exposed shock shaft length (will it move your zip tie up)?

Yes, IRO says they will add .85" to the shock length, so I will have to bumpstop accordingly. Currently as it sits I'm right at the center of up/down travel, which is about 4.25" up & down. With the BPEs, it will be more like 3.4" up/5.1" down. This is something I will have to consider, because I'm not sure I want to give up the up-travel, and I don't want this to lead me down the rabbit hole of adding more lift. I'm guessing that will put me back to having about the same amount of up-travel as a stock Cherokee.

Why BPE's at all?

Good question, and I'm not sure at this point...

I plan to upgrade my LCAs soon, which will increase flex and therefore allow for more downtravel, and that would require more shock downtravel as well. It would be more advantageous to buy a longer shock to do that (increasing overall travel), but my shocks are fairly new, so the BPE would probably just be a temporary measure because I don't want to replace them soon. I have shocks spec'd for 2-3" lift, and they are still my limiting factor even with my modest lift.

This is all just banging around in my head right now. It's something I never would have considered until I looked into the IRO BPEs, because the Rock Roads BPEs added too much shock length at 1.25" vs. the lower profile IROs at .85". I won't make a decision on what to do until I do the LCA upgrade and see where I am at that point.

One thing is you can always sell the BPE's when you get the appropriate shocks. Quality parts are easy to get rid of.

BPE are amazing in the rear, no more messing with those crossmember bolts that are a pain to deal with.

Guess I could. Got a phobia about those bolts to the point that every once in a while when messing around underneath I'll break them loose and retighten them. Probably only been about a year ago I anti-seized them again.

$20 for the front with heim joints.

I was not aware that I would need rear shackles with OME leaf springs. I did not account for the extra 1" lift in the rear.

I will be adding HD offroad no lift shackle relocation brackets, but I will still have to add a small coil spacer up front to level everything out.

After that I will need to bring the front lower shock mount up. 1.5" would be ideal, but 1" is probably going to be it.


I did pick up some new shock bushings already. I ended up going with rubber. I went with poly everywhere except the front shock eyes and coil spring isolators. My LCAs also have rubber on the axle side.

The rear bar pin on the fox 2.0 is very robust. I am going to leave those ones alone for now.
