CJ, how many spring over H3s are in the world right now? Like 10, right? Out of half a million H3s....

WE NEED MORE :)

All True. The SOA mod is the best bang you can do. We also need some more SA rigs! I know of five SA H3s so far...six if you include Brodie's (in progress).

Hard to put an exact number on shock length...different on each build. It has a lot to do with where you weld-on your shock mounts, and also your bump stop height.

I will get there soon and make it 6 :) That is one cool thing about the H3 community. You can have a very unique vehicle with a simple spring over and a solid axle up front. Think about it....IIRC, a couple hundred thousand H3s half a million? I dont remember but alot were made and only 10 are sprung over and 5 have solid axles.

The rancho shocks will work, I have them with my SOA but like CJ said there are variables. I would do the spring over and do shocks last.

How is the axle wrap with SOA on the hummer? I've done SOA on a couple of CJs and YJs and wrap is a terrible issue that must be addressed.

I don't have any. I noticed a tiny bit without the front driveshaft in when running 4hi locked but that's when all the power is going to the rear. I notice none in normal driving with the typical 4hi unlocked. None offroading in lo either.

It may be the fact that the jeep springs are softer. I was concerned with wrap too and already had some ideas to fix it but haven't had issues with it.

I urge people to do it because since I put the rancho kit on in the front and spring over rear I have been able to tackle things I couldn't dream of before.

Getting rid of the stock hangers nets 5.5in of clearance the stock spring sits flatter and gives more down travel and since your using a stock spring ride quality is still good.

Best of all its a good first fab project. I was new to fab and welding and this taught me a lot, it's cheap too if you do it yourself. 300 bucks worth of ruff stuff fab parts.

Next up for me is doing a solid axle swap in the driveway...I think the spring over was good practice for sure and you should tackle this before a SA or do both at the same time

I got zero axle wrap issues. I think this is because the springs are so flat and there are no spacer blocks. Around here the diesel guys seem to have the most axle wrap problems...and they also have big power and those hideous lift blocks on the perches. If you do notice some wrapping...WFO Concepts is sort of known as the "axle wrap pros" and they make some nice torque arm kits. Alot of Jeep & buggy guys seem to run them.

My SA steering is a simple cross-over design. I use a Nissan Delphi box mounted to the outboard side of the frame and a custom pitman arm. You can shave the Delphi input shaft down to mimic the stock rack & pinion shaft...and the H3 column simply plugs right on to it! The pitman arm gets connected to a single-hole, bolt-on arm on a flat-top passenger-side knuckle...via GM 1-ton joints. For the tie rod, I'm also using 1-ton joints and the stock "low-steer" mounting position. I tried to run a high-steer rig but, I couldn't make it work due to the tight clearance. Knuckles are GM...no arm on the drivers-side. No ram yet, although I have plans to add one someday. The stock H3 PS pump works good with the Delphi and it turns 37s pretty well without a hydra-assist.



Sorry...that last paragraph is written in Solidese. The English version would be: "stuff that makes it turn". :)

Interesting. Usually the flat spring is the culprit for wrap. It allows an S shape under load easily. I've had to build anti wrap traction bars on all my SOAs.

Oh, and I want the technical details.. Not the simplified version.

I didn't know you were a Trevor and Beau fan...not my favorite people, I won't use them again ever. But they do some good work, well, Alex is the bomb (I like him).:)

yea, usually the higher arched springs (stiffer spring) help with the wrap issue but I think the all time 4wd helps with wrap. When I ran 2wd I felt a tiny bit of axle wrap during hard acceleration, not so much during normal driving. Once I threw my front DS in and had awd back the wrap went away completely. The H3 uses a soft spring but even the V8 H3T with a spring over rear solid axle swap up front had no complaints on axle wrap. Not sure why...I sure as hell thought I would be looking into traction bars after my spring over but have had no issues. I have yet to find a downside to the SOA. High speed may be one...My thought is that when jumping all the load is being transferred to the axle tubes instead of the spring but thats a totally different topic.

I would do the spring over again on any additional H3(T)s I own in the future.

I might be simifying to much or might have my wires crossed but, on a SAS we are using stock springs and cutting the mounts.. Is it possible to use springs from a full size truck or larger to create more tow capacity???

Also is there a way to create a little more hight clearance since the T has a longer wheel base but low enough u can still level out with te rancho lift???

Well you can use a different spring but you will be pioneering it. No one has done a 63in Chevy spring swap...

We just got a new offroad shop in TK called TWs 4WD and Desiel... Never heard of them until now but they seem to be doing good because they have moved to a bigger shop in TK.. I called and asked what all they do and they said anything.. I asked about the SOA with heavier rated springs like 3/4 ton etc. for more tow capacity as well as offroad ability.. He said he said should be no issue but they would have to get under the truck to confirm. I will gather as much I go as I can so I can attempt myself...

So a Co-worker pointed out to me today that my truck is currently leaning quite a bit. I thought to myself,”yeah I know he is talking about the rear and it’s getting pretty saggy.. that’s what he must be talking about…”
Nope! Check out the hub to fender measurements! :O

Rear Left- 23 ¾”
Rear Right- 24 ¾”
Front Right- 25 ¾”
Front Left- 26 ¼”

I am sagging hard to the rear left! (This is with the 4” Rancho Springs!)
Is there possibly something broken that I should be checking on?
I am going to check the leaf pack and make sure that there are no broken leaf’s… anything else?
I think the answer is SOA with AAL & it’s back in my to do list in the very near future!So a Co-worker pointed out to me today that my truck is currently leaning quite a bit.
