True that!

No one's mentioned it yet, so I'll just throw it out there, that lip is for maintaining hub centricity between the hub and the duals. It is (naturally) larger on a DRW hub as it needs to center two wheels as opposed to one. GM hub bore for those wheels should be 4.56" if I remember correctly. An adapter or spacer with that ID shouldn't have any interference issues.

The adapters are designed for and fit perfect on DRW 14 bolt hubs, the issue is with the 3/4 or 1 ton SRW hubs. I have never tried to fit my OEM dual wheels on the SRW hubs but I would guess if they are hub-centric they would also have issues with that lip.

My factory DRW Dana HD70 has that lip as well.

That is odd, when I was measuring both SRW & DRW hubs for my spacers I measured squares and GMT-400s, found them all to be right at 4.56"...it was just over 4.5" but under the diameter of the lip on a GMT-800.

[75Dually]

This is why I like this forum so much. The guys here are so helpful and knowledgeable. I need to get back into the shop... Thanks everyone for their help and assistance!

[75Dually]

So I got out for lunch today to take my son to Academy sports to get the last items for school, so I took the dually to make sure that I had no more vibration issues. Whew it looks like that did it! I still have to go get the front end aligned, but at least that is a normal part of any vehicle.

Now I can get on with some other projects, the bed, AC, finish the interior... You know simple things like that!

Not trying to muck up 75Dually's thread more but I guess I sorta am anyways.

This is the DRW hub









And here is the SRW hub turned down to fit the adapter.




Both have the lip but the SRW lip needed to be turned down. I didn't measure it before I had it modded, I just brought the adapter with to the machine shop and asked for an almost press fit to keep it hub-centric.

Great pics I'm impressed! So for those of you out there with 3/4 ton rear ends and SRW rear ends pay attention!!

[Ghostwhite]

Oops, forgot a pic and somehow posted one twice.

[75Dually]

So I have been really busy in the shop in the evenings. I know I have not posted anything in quite a while, but I do have something big on the way to show you guys... I just did not want to show this until it was all done. I hope your going to like it!

STAY TUNED....

[Dieselwrencher]

What a tease! I hope you guys get some of this cool down that we are getting up here. About time. Ha

That's why I'm in the shop so much, the weather has been great!

I can't wait to see what everyone thinks about what I'm working on. This is going to be polarizing. Either your going to like it or not... Either way the opinions are going to fly!

Oh now I'm being a tease again! Dang it!

Stay tuned!

polarizing...Is that a clue?

It's more a state of mind. Seems people today choose one side or the other on any subject... You'll see...

Nice try though, next contestant! Just kidding...

[75Dually]

OK I decided to give ya'll a hint. The guys on Garage Forum were dying to know so I gave them this pic tonight after all my hard work today. Yes it is bigger than a bread box, and it's under that blue tarp. Let the guessing begin!

[daddyjeep]

Nice Tarp. I like what's underneath too.

[COS399]

I used to have one just like it.

[75Dually]

OK I caught a nasty chest cold and I can't work on the Dually for a while. However I have been wanting to do a video build series on it from the beginning to current day. So I got part 1 completed tonight. Check it out and let me know what you think.

I should have the mystery item completed in a couple of weeks, health permitting!

Stay tuned!

[daddyjeep]

Thats cool. I like the idea of a slide show of the build.

Thanks! That way I can use all the old build photos and keep the timeline consistent. It was interesting trying to weed through the big file I have on this build. I was going through it and saying hey I remember that! I'm am however glad to be further along and it being a driver now. I still have a bunch more to come in this series. Should be interesting!

[75Dually]

PART 2!!

Check it out!

Super glad you liked them! There should be a couple more parts to bring it up to current day out real soon.

Thanks again!

Is the mystery item a topper or a sleeper?
