What parts do you want for your H3?

[amrg]

1. IFS diff upgrade (stock or rancho compatible). That would mean the weak front diff, something stronger and regearable (for alpha ppl 4.88 will do for 37s, I5 ppl will want a 5.13).
2. Rebuildable UCAs?
3. Long travel from IFS, although I feel the Diff and UCA are higher in priority (not alot of ppl want to move to SAS, although its the best upgrade)

Some way to more efficiently cool the H3 other than throwing on an external transmission cooler and cutting holes in the hood. I realize those might be the best way to go about doing it, and that we aren't GM engineers who design cars for a living haha.
I just feel that there is a better way to go about fixing the cooling problem.

This is how its done here, 120+ degrees summer here and my engine doesn't go above 210 under heavy load. Offcourse Ive never seen 210 before I flushed my radiator and changed the thermos (new thermos are 190f while origonal ones are 180)

Idk how functional it would be, but damn it would look cool

Ahhh yes. That should be the official Hummer slogan. -LOL

I would say Fender Flares and tube doors would be nice as well

Even though i don't have a H3 any more. Steel fender replacements and body armor would be nice.

Portals?

edit: Screw it, a whole new front end.

Portals are gona be expensive!

 

[2010H3TAlpha]

A hard canopy that isn't slanted and doesn't cost an arm and a leg.

So is a whole new, stronger, regearable front end.

 

[derian06]

I read all of bebe's build thread, weren't they going to make a kit for the front end?

 

[kilroy]

Re: Portals, don't know if they're still around but Atomic Axles looked pretty strong.....then again so was the price tag. A Dana 44 wouldn't be too pricey but to convert it to a matching ifs would cost some bucks. The machine work alone would probably make most guys forget the project.

Amc-20!

 

[digglesworth]

Some full coverage ucp for the rancho lift...

I'd love that!

 

[chad]

here is an opposite of what most guys want but since the h1 is independent front and rear, how would independent rear be? at least no more leaf springs.

 

[06 H3]

Too much work for not enough gain IMO. Keep it simple. Rancho front, spring over rear, AMC-20 front (no portals just the diffs) regeared with 5.13s run 35s-37s make some beefy tie rods and steering rack brace kit. Lock up front and rear, the front locker will help with the unloading issue on steep hills. disco the sway bars and drive smart. You will have the ultimate dual setup and its relatively affordable compared to what other vehicles need spend to make something that capable on and off road.

1) Compatible bushings and balljoints for the upper control arms. Still delaying buying a pair just in case.

2) Front diff assembly that allows bigger gears!

I was looking at that. At first I was like, meh. Then I see the gear ratios and remember I wouldnt need the two-piece axles. Plus I think some were the right spline count too. Hmmmmmmm

 

[4speedfunk]

Lowest you can go with the AMC-20 is 4.88s but, that would work great for most of us. Splines don't matter because the H1 diff comes with stubs and flanges already designed into it. You would have to run custom half-shafts (similar to Bebe's)...so they would bolt up to the flanges on the inboard end, and still fit the unit-bearings on the outboard end. Lots of mounting bungs all over the H1 case, so I don't think it would be too tough to engineer a mounting system.

There's a place about 30 miles from here that crushes H1 diffs by the thousands. Sigh.

4.88 is a fair compromise esp if the diff is stronger than the one its replacing (for me at least as it would be replacing the Alpha 4.10s). Keep us updated if ypu decide on ur next project!

I see that both the AMC-20 and 8.6 have 5.13 gears available, that would be my choice. I thought splines were both 29 but the H3 is 26 spline. Not a big deal, I don't care about off-the-shelf spares, I would have another pair of hybrid half shafts made up as spares.

Are we still talking about swapping the stock front for an AMC-20 center section with custom shafts or for a H1 front end? I thought we were looking at having to swap pumpkins, machine up new axle shafts/stubs and new half shafts? Of course it all SOUNDS easy.

Edit: I'm finding references to gears by Shafer way back when but nothing currently available. Oh well, more urban legend.

 

[atvspeed4]

You cannot get 5.13 gears for the AMC 20 as stated above. Also would need a custom lift kit similar to Rancho drop crossmember to get diff to fit. The H1 diff housing is pretty big and will not fit in stock height H3 unfortunately.

Yes.

...or for a H1 front end?

Yes...same thing, (an H1 diff is an IFS version of the AMC-20).

I thought we were looking at having to swap pumpkins...

Yes.

...machine up new axle shafts/stubs...

No...it comes with them.

...and new half shafts?

Yes.
