[HummBebe]

I'm about ready to blow a gasket on this one, so I'll KEEP sitting this one out.

You as well as Sledgehammer caught me. It is a 2.64:1 BW 4493 and the off-road is BW 4494 4:1.

I wonder when we are discussing the underbody protection if the original poster is asking about the three shields that do come with all H3s; the front shield (with the H2 on it), the shield Sledgehammer ripped off (as shown in another thread), and the thin one that hangs under the Tcase?
The caged underbody protection is optional on all vehicles, but should be a requirement if doing any serious off-roading.

I believe they go into more detail at Hummer.com but not sure.

Correct...all get the 4.56 gear and the adventure series (or off-road package) get the 4:1 Tcase versus a 2:1. </div></BLOCKQUOTE>

I wouldnt be so sure, I think it's 2,62 (or 2.72) on the base package. I have the adventure package and it doesnt come with an underbody protection.

I already ordered the underbody protection from GM and Offroad lamps & rocker panels. will be taking before/after pictures as well as installation pictures, will post them when done, not sometime soon though.

Hate to tell all, but a few weeks ago this popped up in the tech section, and I confirmed with the engineer in charge of axles, and there is only ONE axle ratio offered on the 2006 H3 Hummer; and that is 4.56:1.
This is irregardless of what a marketing sheet has on it. Prior to calling, I had pulled vehicle information build sheets for autos, manuals with and without the off-road package, and found only 4.56 gear listed. </div></BLOCKQUOTE>


Interesting on the auto vs. manual rear end ratio.

1. A little suspect though, since we are hearing that gearing in 5th gear on the manual tranny is considerably taller than 4th on the auto tranny. Based on the chart above 5th gear should be slightly lower given that rear end ratios are the same.

2. It's very normal for auto and manual setups to have different final drive ratios.

The engineer might be a little drowsy. Nudge him to recheck.

I should keep out, but I won't. The engineer in question is the head service engineer for this part, he is a manager, he is also in charge of the release of this part to service application. He assured me it was a 4:55:1 gear, and this went right along with all the vehicle history build sheets I pulled up in the system.
In my opinion, I don't need to nudge him. Maybe those with all their innuendos and assumptions should get nudged a bit.

Partial copy of my Build sheet, H3, auto, with off-road package:
G94 - LOCKING DIFFERENTIAL HC4 - REAR AXLE 4.56
JB9 - BRAKE LIGHT JJA - PT DRESS SUBASSEMBLY INSTALLED
JL4 - STABILITRAK-STABILITY CONTROL KA1 - FRONT HEATER SEAT
KG7 - 125 AMP GENERATOR K05 - ENGINE BLOCK HEATER
K34 - CRUISE CONTROL L52 - 3.5L DOHC 220HP ENGINE
M30 - 4-SPD AUTOMATIC TRANS W/ STABILITRAK-STABILITY CONTROL NP5 - LEATHER WRAPPED STEERING WHEEL
NR6 - 4:1 TRANSFER-CASE NT9 - FEDERAL EMISSION SYSTEM TIER 2


Build sheet of a H3, manual, off-road package:
FE9 - 50-STATE EMISSIONS HC4 - REAR AXLE 4.56
JB9 - BRAKE LIGHT JJA - PT DRESS SUBASSEMBLY INSTALLED
KG7 - 125 AMP GENERATOR K34 - CRUISE CONTROL
L52 - 3.5L DOHC 220HP ENGINE MA5 - MANUAL TRANSMISSION
NR4 - 4WD TRANSFER CASE NT9 - FEDERAL EMISSION SYSTEM TIER 2


These are the actual build sheets produced when the vehicle is run down the assembly line.

i put Terra Grappler 33's on my base H3 with no problem. truck runs great. other than the obvious lack of power complaint by everyone, i don't notice a problem. i did raise the torson bars up an inch in the front...rides great.
good luck

[HummerJim]

Fstop is there any truth in the statement a salesman made to me that the Adventure package has an extra leaf or stiffer leaf springs? Is the suspension difference just in the shocks?

And are 33's really going to rob noticeable power from me if i upgrade from the stock 31's down the road?


I thought the base had 32 inch tires.

[HummerB]

again............what is the difference between the two transfer cases.......i guess what i am asking is what do the numbers 2:56 and 4:1 mean??

[UNOMYFLO]

I almost forgot it also gives you the dash actuated (by button) rear locker...again a lot of bang for the buck.

If you added up the cost of all the parts plus labor there is no way you could get even the parts for 3 grand.

All I'm saying is that two months ago (not that long ago) they were NOT all 4.56 geared H3s on the lot. I looked at a lot of windows. This made me look up the page I found and they do indeed come with both. Checking your sheet before you buy one is the only way to know. There's still H3s on the lot as we speak with 4.10 gear ratios. </div></BLOCKQUOTE>


Huck BB62, got it. I checked the sticker from my H3 base automatic and it says 4:56

Neocon1, that's the beauty of the adventure package, the granny gear is extremely low and with it engaged it doesn't matter what your tire size is or what the rear end ratio is (within reason of course) .

I agree with the previous posts and wish I would have gotten the Adventure package in June! It's a bargain for all they give you. I also believe the salesman told me the Adventure has one more leaf or thicker leafs?? They only had one at the dealer and I thought it rode a little stiffer, but have ridden in an Adventure H3 since, at the Ozark Offroad Bash I can now barely tell the difference in the ride with it and mine. I have added slightly larger offroad tires and with the stock gearing the acceleration has suffered a little, but perhaps the highway mpgs have improved, because I get consistent 17s on the highway. Go with the Adventure Package!

[NEOCON1]

all i know is i took delivery august 30th . mine is an auto if im in 1st gear in low range i can go down STEEP and i mean REAL STEEP $HIT no foot on brake and doubt that the truck exceeds 2-3 mph i think its incredible .
