I need to correct my statement, the saddles underneath are fine, its the plates on top of the perch that have begun to warp. With no positioning pin or dowel they are held in place by hopes and dreams and are pretty thin for my purposes. Most aftermarket parts arent meant for racing on these trucks, kind of a newer market so options are limited. Hoping to have something better fabbed up soon.
I was looking for a fix and have seen where some eliminate the perch entirely by putting actual rounded U-bolts over the axles on either side; in fact crown suspension uses this method for their rear flip kits, unsure if other brands are doing this as well.. but i like the idea of custom perch plates with welded guide dowels like you did.. I may be having some fabbed up after seeing your post.
I was going to mod my plates with a locating pin before I installed them, I just don't like the idea of them just sitting there. I think i'm going to swap over to the round u-bolts, I like that idea.

This is why when I put in the IHC performance kit this weekend I will be using the rounded U-bolts and locking it straight to the axle. I may or may not swap out the saddles. It depends on the condition and if the angle is much different because I've had zero issues with the Maxtrac saddles.
Let us know how it goes with the round u-bolts.
I found a pic of my install and it looks like the round ones on the axle tube should work with no problem...

. At 5:24 he explains how he was having a bunch of loud noises in forward and reverse and says it was due to the round U-bolt setup we were just talking about. You can see the axle tube spin briefly with what seems like everything attached to it, leaf springs, relocated shocks, just slapping. I don't quite understand how this is possible since the saddle should be keeping the axle from moving in either direction with it being up in the spring perch like it is. But then again, the saddle shouldn't be taking that kind of stress anyway...which got me seeing the necessity of using the spring perch plates with the square U-bolts...it just holds everything to the axle so much better in either direction. Then I got the idea of using the stock 2021+ top U-bolt plate (see picture) to use with the round U-bolts as a better alternative to the IHC plate. I might even have it welded to the spring perch...

That is weird...I don't know either, how the axle would rotate just by being clamped down on the sides instead of in front and behind the tube. Like you said, it's still sitting in the saddle which should not be letting it move at all. I think I might still try it.
If it makes more noise than what I have now, then i'll try the 2021 u-bolt plate (nice find!)...and with it being bolted right to the spring, maybe the holes will line up with the perch on our axle which would make locating it a lot easier.
So I just found this video here. At 5:24 he explains how he was having a bunch of loud noises in forward and reverse and says it was due to the round U-bolt setup we were just talking about.

I dont know what could be wrong with his setup, but my RideTech kit uses round bolts that go over the axle and I do not have that problem!
If you watch the video, he was getting a mad amount of movement (rotational) from the axle. The saddles should not be allowing that at all. Whatever he did, I doubt the square bolts would be the true fix.
Thats what Im wondering also, the ridetech kit is what made me initially look for the round u-bolt setup, the rear drop and the tracbars on the ridetech all use the rounded ubolts over the axle, so should work...

Just finished my VAS Flip. I'm having vibration issues so I came here to see about the carrier bearing relocation. I wish I knew about the ridetech style flip it earlier.
I like the extra piece removed from the equation although I'm not sure if it could impact rear end control. No wonder their traction bars are different.
As far as the Vas kit, The Vas top plate has bolts in the top plate location holes to keep it located. Seems to be pretty thick compared to these pics as well.
, it works so far. with a vibration...which I will fix with other manufacturers instructions. Most likely the belltech carrier bearing mod. I'll try that next.
