Need help quick please, axle U-bolts

[Wild83C10]

The thread diameter and axle tube diameter is correct, not sure about the length though.

Can I make another suggestion. The best flip kit is to weld in new perches. You can get the correct pinion angle and it's much safer. It's also cheaper.

What do you do about the offset hole fr the spring center bolt?

I already have the flip kit, so I am going to use it. Are you saying the flip kits on the market are not safe (and all the trucks running them), and make the pinion angle incorrect? I hope not. This is going on my 6 cyl truck, not the BB truck if that matters.

Hhmmm.... a manufactured/engineered bolt-on flip kit vs. a spring perch that's been welded on by who? I'll take the flip-kit & not worry about it. As N2Trux mentioned, the other benefit of a flip-kit is the slight relocation of the rear axle C/L to help center the wheel in the well.

Your going to tell me every flip kit out there is manufactured/engineered properly? I have seen some pretty poorly built flip kits out there. And if someone is dumb enough to have the perches welded on by a novice then they shouldn't be modifying anything on their truck. I would just hope they don't hurt anyone else when something goes wrong.

We're speaking of manufactured parts right & not home built? I wouldn't buy a cheap flip-kit just like I wouldn't trust just anyone welding new spring perches to a housing tube. And you can rip OE or 'retro-fit' perches off when they're not welded correctly.

Wild83C10- Here's the reason Scoti is posting in a defensive manner. You throw a casual suggestion out about "The best flip kit is to weld in new perches" with out offering any further detail. We know that most of the guys that post on here know that they should be welded be a competent welder. We also know that to do it this way, you need to set the pinion angle, as well as address the center bolt issue. Unfortunately there are those that just read this forum that might not know all of this VERY pertinent information.

I agree that a few dollars can be saved by purchasing a cheap set of spring perches and welding them on. I also know that if you don't set the pinion angle correctly you will have the potential for driveline vibration. Combine that with the fact that you still haven't addressed the center pin issue, and suddenly the $60-$80 manufactured flip kit starts looking like a better value.

So my point is, if you want to offer the weld in spring perch as a viable alternative to a manufactured flip kit, please offer a disclaimer to go with it. Or better yet, write up a nice "How To" with pics so we can add it to our forth coming Suspension FAQ....

I didn't take SCOTI's response as defensive. I know you are an adminstrator and all but do you think you should be answering for other members? I know you and scoti are friends, but it's still not right. I certainly don't want you answering for me.

So are you going to tell me that everyone making a suggestion has to post every bit of information about it? Along with a disclaimer? I have seen plenty of members post suggestions and not provide all the details. I don't see you telling them what and how to post.

Maybe you should put a disclaimer at the top of the tech sections, stating that the information contained in these post should be verified first.

To answer one question:
I don't recall how I addressed the center pin issue, as this was done years ago. I was mearly making a suggestion and if he wanted more info then we could workout the details.
