I'll take pics of mine. Shouldn't be too hard to fab something up on your own.

i found a picture on the internet. I could use the 1/4' plate to make it strong enough

back to the drawing board. This weekend one of my upper rear mounts failed just shy of the racetrack in death valley. From what it looks like and what I'm told it appears a weld fail is the root cause, but its also shown me the stupid amount of stress this mount is going though. My minimalist plate mount isnt going to make me feel confident anymore.
First up is the carnge pictures. This happened on a bombing run from Ubehebe Crater to the race track. I wanted to do my planed three day run in just two days so I was letting the tires and the suspension feel the pain. In another tidbit of humiliation I had just run down a jeep trying to make a speed record of his own. I carefully worked up through his dust and made myself visible. I saw him look in the mirror and then he just tried going faster...so I made a pass worthy of a baja race lol. But a fun as that was it was all for nothing when he passed me back as I inspected the damages trailside. (side note: I have no idea why people dont pull over like I used to when a faster truck comes up from behind. I actually find people will drive like idiots in every effort to not allow me to pass. Are we really racing???)
you can see here the upper weld is pretty crappy. I knew it was substandard, but had figured the mount just needed to be strong in compression and the rebound forces would be minimal. As you can see the 1/4" plate was bent right over via the rebound.
turns out the shock is fine. This is just tire marks on my clear vinyl sticker protection. Luckily I stopped in time before it was damaged. Unluckily a rouge shock smashing into your wheel well makes enough noise its hard to ignore.
My next mount will be similar but will not be relying on the single brace to save the day. Unfortunatly I do not have a tube bender because I understand now thats the lightest and most fool proof design. My original thoughts on the plate mounts having desirable location benefits turned out to pointless when the shock contacted the frame under flex. I'll post up more on the new mounts this week, but its going to be more 1/4 plate.
I had planned to film the whole trip, but all I really got was Titus canyon lol.
Awesome video, Troy! I loved Death Valley when I went a few years ago. It was way better than I expected it to be.
Bummer about your shock mount, but it's great that the shock was fine.

The video was awesome! Too bad about the shock mount. I give you props for all the work but it's amazing that you folded up 1/4" steel like that.
I'm very new to making fab stuff but is there any way to triangulate the mount to deal with the stresses? It's hard to say what I mean but possibly extend the actual shock mount weld to the top part of the frame as a gusset and perhaps put another wall on the outside of the mount with a few horizontal braces between. It would allow for flex a little but it would reinforce as well. I probably couldn't weld it up either lol. I'm sure you have a good idea of what you need though.
I'm still amazed that you broke that mount. Definitely want to see the new design.

it was nuts and the last thing I expected to find when I heard the noise. oh well it was a cheap lesson to learn as far as truck things go. I'm just tired of re-working those mounts.
The new one will just have more braces sorta like I think you are talking about. A second brace on the back and one on the front should work well and never allow it to free float on a large fulcrum again. I believe it will be overbuilt but in a worst case scenario it should bend and not have a chance to hinge and break like this one.
Ok heres round 2 or 3 if you count v1.1 With any luck this will be good to go.
Yep that wasn't far off what I was trying to describe. That's a BEEFY mount! You have even more bracing than I thought about. Looks great!

Great video and great job on the repair. The original does look like the vertical weld failed then the pushing and pulling from the shock broke the piece, nicely done.
Your repair looks solid and it looks like you jumped right on it. I think capping it and adding the triangulation will stiffen it up a ton and give you better results.
