X2 on the hubs

 

I'm just kinda leery about threads holding the weight of the vehicle.

 

if a Poly spacer can hold the weight then a steel thread can hold it too

 

That can be argued.... There's a lot more surface area holding the weight in a poly spacer than a threaded adjustable spacer

 

You guys are crazy if you think that the threads are going to fail. From the picture it looks like there's about an inch of threading. That's a lot of surface area, I'd venture to say it's almost impossible for those to fail regardless of what you put your rig through. I mean, they use aluminum ones on coilovers that handle incredible G-loads on a race track. I just can't see a similar design out of steel breaking under any conditions. I also did a quick google search, and I can find no record of a threaded sleeve like that failing at the threads.

I don't know what you're basing your objections to the threads on either. I mean, do you guys often see bolts where the threads have just been pulled off by the nut? Stripping threads by over tightening is a different story.

I think it's more likely that the threaded nut breaks than anything else, and even that seems pretty outlandish to me.

 

Funny cause I just ripped the threads on 6 bolts on my rear bumper.........but anyway nobody said they would fail. I just said that I was leery about it.

 

you ripped the threads by over torquing, not by pulling or pushing on the bolt though, right?

 

I've used the adjustable spacers for circle track and road race applications. They are not for road longevity. They do allow suspension tuning to differing tracks and track conditions. I don't see the point for my XJ. I want my jeep up and have no intention of adjusting once it's there. Nothing wrong with those adjustable parts, XJ is just not the application for me.

 

No. I ripped them through. It was not from over-tightening. They were threaded through an aluminum flat plate then had lock washers and nuts on the back side of the plate.


Exactly. That's why I'm thinking of making a spacer that's not FULLY adjustable. If you would need to change the height, you would have to pull the coil.
