Diff. btw std supension and off-road suspension?

[HummerB]

What are the exact upgrades, besides the 33 in tires and underbody protection?

The adventure package comes as follows:

1) 33" tires
2) 4.56 gear ratio (probbaly due to the larger tire killing the stock gear setup) Plus more offroad ability gearing wise.
3) stiffer suspension and shocks.
4) different (lower) gearing in the transfer case.

I think all H3's have the 4.56 rear end ratio, only the granny gear ratio is different between base and adventure setups.

Better check your build sheet. From what I saw at the dealer, 4.56 gears are found on the Adventure package.

Wrong, read the sheet.

All automatics have 4:56 rear ends (both base and adventure). This chart is showing different gearing of AUTO vs. MANUAL tranny.

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

[Hummer Guy]

The undercarriage protection on the adv. is no different from the base. The shocks are tuned to be more stiff and give a more responisve feel when off-roading. Personally, I can't tell much of a difference in ride quality.

No, another difference is the Eaton Electronic Rear Locker in the axle differential.

Correct, upgrading to 33 in tirs is no problem. As for acceleration, not sure you would be able to tell the difference. Besides the standard tires are 32", off-road are 33." Biggest difference between the tires is the 33s are Bridgstone and are better for off-road than the Goodyear Wrattlers on the standard package.

[f5fstop]

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.

[Huck BB62]

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.

[H3HUMVEE]

the base hase a 2.64:1 Borg-warner transfer case

[NEOCON1]

acceleration and hummer in same sentence you guys are a riot . and whoever said lack of power dont you know what these were designed to do ? LOL you guys should get the 32's your trucks will be so fast

[HummerB]

by the way i did a search but the answers i found are a bit inconclusive. I understand the rear locker, 33 tire upgrade, and underbody protection come with the adv. package. Is this the only difference?

[fourfourto]

You also get carpeted mats and you get a left rear compartment unless you have the monsoon stereo.

Front:
w/ 32-inch tires: 24 / 609.2

w/ 33-inch tires: 24.7 / 609.2

Rear:
w/ 32-inch tires: 24.5 / 623.5

w/ 33-inch tires: 25.3 / 643.5

There are no 31 inch tires You get the rear locker also.

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?? </div></BLOCKQUOTE>

Well, in simple terms with the 4:1 for every four revolutions of the input shaft of your transfer case you get one rotation of the output shaft ..So you can reduce your output ratio from your transmission by four to one...

[SledgeHummer]

hehehe H3HUMVEE you bad bad boy, that's the answer he's looking for

What HUMVEE is trying to tell you, the higher the T-case ratio is the stronger the case is. i.e. in rockcrawling condition or extreme offroading conditions the 4:1 case gives a lot more power than the 2.64:1

[HummerB]

i am not interested in being fast, but i just dont want to hinder stock accl. ect....
