So I've been offroading a few times since I've installed the Pirate Procomp/Bilstein lift combo. Love the ride. I did not install a rear top plate that accommodates for a bumpstop. I always noticed that the shock was close to the axle. But on this last trip down to Baja, it rubbed enough to blow out both the shocks. I examined it and it looks like the lower shock mounts had broken where the tab on the axle holds it in place. I'm assuming this is from bottoming out the shock.
I'm planning on just rewelding the tab bracket on the lower shock mount to fix it.
Is there a Bilstein 5100 shock that will give me more travel?
Should I install a top plate for the leaf pack that will accommodate a bumpstop?
Just figuring out how to prevent this from happening again since I drive it pretty hard offroad.
Thanks for your input. Lower shock mount turned quite a bit. Install plate for bump stop?
Do you know that you have the rear angle shim installed backwards? And that flattened / pinched brake line in the third pic would give me cause for concern.
Just out of curiosity, why so many washers under the u-bolts nuts? Where the bolts not threaded far enough down?

If you are running 5100 in the rear then they are likely to long if you have 4" or less lift. Once you get your mounts fixed measure the sitting length, collapsed of the 5100 is 20". I found the 5100 to be too long on my 4" lift only leaving 4" of down travel before bottoming out.
To answer you question there is no 5100 shock that will be (shorter) to allow more travel. That's why I going to 4600.

Man I was hoping no one was gonna throw me flack for that but oh well. Good eye! I know the shim is backwards. It never gave me drive line vibrations so I never got around to switching them around correctly. But if I install a top plate with bump stop, I'll flip them around and put new U bolts on as well. Yeah those are actually the stock U bolts. The ones I purchased for the lift were too long. That was a temporary fix that turned into longer period. And the boot that was on the shock caught the brake line a while back. I plan on replacing that along with all my rubber lines.

I agree. I have 6" but this is with the bracket twisted too much. Would it be bad to have 5100 in front and 4600 in rear?
From bilstein wedsite they say that 4600 are for stock height and 5100 for lifted but other than that neither is better than the other. This will be the set up I will be running 5100 front 4600 rear once I finally get the correct lengths. https://www.bilstein.com/us/en/faq/
It looks to me like the mount just rotated either because the mount wasn’t tight or indexed on the tab correctly.
take the mount off the axle and investigate,
if the mount was on correctly it would have beat the end of the shock up or bent the shock shaft if you bottomed out. I don’t see evidence of that in these pics.

I examined it and it looks like the metal inside of the bracket that holds it on the axle tab is broken on both sides, causing it to rotate. I'm assuming whenever I would bottom out the suspension, the mount would bang on that axle tab and it eventually broke.

35" also. I would run the 4600 for the exact reason give in this tread, the 5100 only has 4" of collapsed travel in the excursion. This is at a 4" inch lift. The OP maybe looks like 2"?? (Hard to tell from pics) so with the 5100 I would be guessing 2" of travel until bottom out.
The 5100 and 4600 are the same per bilstein per link provided, only difference is shock length, also answered previously.
Adding a picture of how the 5100's (33-236964) look with just body weight on even ground, the white string is where the bottom of the shock body is.
