Anyone use these?

Curious what others think of them. If i see it correctly, the perch is welded to the tube, but there is a complete lack of ubolt use around the axle. This scares me.

The perch changes from a perch, to a spring mounting tab.

What happens if your perch weld fails? The axle falls off your truck?

I wonder if this is even street legal.

With what we do to our rigs, i wouldnt' trust a setup wiht no ubolts. The possibility of your ubolts failing is way less than this style.
 
Thats what I'm doing. the tnt customs version. They make em in different heights too.

My buddy has them they where installed in 2009 and no issues yet.
 
It looks more for lightweight setups. For me I'd probably add a few gussets from the user side of axle tube up to the weight distribution point. It looks like one of those things that will work perfectly, up until it fails, and then it fails spectacularly.
 
Seems like the offset would add....alot....,maybe alot is not the correct word, but more leverage on the welds then an on center type pearch has. Granted they are a good portion of a circle's worth of weld length. It better be a good quality weld, thats for sure. I like the idea though. I too prefer a U bolt though. A better idea might be to retain the U bolt but allow it to rotate forward or backward around the axle tube, yet still be there. The top plate would have to have some huge angle to it, and it wouldn't be clamping down in a straight line, rather it would want to slide down the spring. Don't think that would work actually. The spring pin would be put into a shear situation and may be dangerous. How would this effect axle wrap? Would it create more or less leverage to increase axle wrap or decrease it?
 
well, it does mention Samurais, Land Cruisers, and Jeeps as their target for these. The Land Cruiser might be a tough heavier than the other two, but still lighter than full sizes. Dunno, I wouldn't change my offset zero rates for them.
 
I have built stuff like that before. On full sizes, never had one fail. I don't think I would worry about it.

One I built has about 4 years of hard wheeling on it, no problems at all.

Before he sold the rig I would occasionally inspect it. No problems at all
 
Theres no reason you cant run U bolts on that. Just have to run squared ones with threads down. Shouldnt really matter since its way about axle cetnerline anyway.
 
I don't see a problem with not having u-bolts. Last time I checked four-links don't have them and the tabs are just welded to the axle...:whistle:

Good point. But the forces put onto a link are way different.
 
Idk Ive heard nightmares about eliminating u bolts and Ive heard good things about it. Ive never experienced it first hand so I couldnt really say but the force is in no way similar to bolts through a rod end.
 
I've thought about building something similar without the offset to ditch my ubolts for years. I've just plain had bad luck with them over the years coming loose. Plus it'd be easy to carry grade 8 bolts as trail spares.

That's why I'm going with them. Easy to carry spares and if a do need some, I can run down to the hardware store and get some for a couple bucks.
 
I would think good grade 8 fine thread studs with nuts might be a better option than a bolt. A Stud should be you some more stretch similar to a U bolt.
 
What I don't like is the threaded 1/2 inch plate, I don't feel that's enough thread engagement. Basically half the threads of a good u-bolt with tall nuts.
