We ran their HD option on our 6.0L H3

Our best guess right now on the issue of the CVs is that of the four H3s that have run the diff, the three that did not have a problem were running our prototype billet aluminum sleeve/ UHMW carbon black lower control arm bushings. The truck we had at the vermont pilgrimage overland event in the...

Have not been able to figure it out. Same vehicle, same bushings, same housing, same part number cv shafts. Really frustrating we have crate of 5 housings and custom machined shafts just sitting collecting dust. One of our friends is running one in his H3 to log miles and trail time to see if he...

There is a company that makes a conversion kit for the H2 that allows install of 4l80. Kit for H2 It has a 27 spline output shaft and harness I believe. You would need to make a new transmission crossmember like we needed to do for our 6l90 swap along with transfercase adapter since h3 is 5 bolt...

You do not have to do that at all for a swap in a 2006. We swapped a 2011 6.0 and 2012 6l90 into our 2006 without running two pcms. Sorry someone gave you bad information its tough with the internet navigating something like a swap with so many different information sources. Check out some of...

We have had a 2006 3.5 in our 2007 for many years. This was a direct swap but it is harder on the 2008+ 3.7L

I'm just trying to give advise based on years of experience going down this rabbit hole. If you do a search on the forum you can see how old the threads are from those of us that have been modifying this platform for a very long time trying to solve this very issue. The ring gear is not the...

The 8.25" is junk and also like to explode I wouldn't waste time on that especially with the work for building a custom lift kit to try and get low enough to clear the steering rack. I'd rather run a Alpha cast iron diff than the 8.25". I've spent enough time wheeling with half tons to know not...

Thats correct only happens at full compression. The bump stops are GM ones and only about two years old and less than 1000 miles on them. We are definitely not giving up but this is a tough one as its hard to guarantee that all buyers are going to have good bushings before installing diff...

The diff bushings are non-wearable and won't compress but the lower control arm bushings are stock with 140k miles on them so you might be right that might be it allowing arm to move up higher in the bushing

Exactly! All ideas are welcome we are baffled after such a long time why this would happen

I remember him from the early days of lurking on colorado forums for 5 cyl tech. He used to sell a turbo manifold and injectors for the 5 cyl was really nice guy answering all my questions but we are talking a LONG time ago

Went to the Vermont Pilgrimage overland event and blew three cv shafts as they came in contact with the lower control arm cross piece. This has never happened in 6+ years so we are trying to figure out what changed on the truck to cause this. Other than that everything is working perfect no leaks

PM sent sorry for the delay just found them in storage

Yes they are. Just curious is yours a 2009 black h3t?

I have cloth h3T headrests if you are still looking

Chris it was Jamie. When I had my 06 5 speed I was going to do the swap and talked extensively with him about it but ended up selling truck to my friend. He has it figured out

Well my wife needed a new car finally. After many years of daily driving various H3/ H3T on 37s we decided to give the new EV a shot to see how the electric life goes. It isn't the fancy 3x model with offroad package but this will just be her daily driver for now. Will let you guys know how it goes

Steering rack stops a driver side drop from working unfortunately. We already tried that and it would not clear.

Bushings are now in stock but we are sorting out the freight currently. The company we were using for our S10 diffs is no longer shipping one off pieces freight
