hummer H3T

Le ratio des ponds est 4,54 pour tout les 3,5 et les 3,7 , seul les alpha on un ratio de pond de 4,10, c'est du au couple du v8

Pas 4,54 sorry mais 4,56 :1 tout les 3,5 et 3,7 et 4,10:1 pour les alphas

Et il s'agis de ratio de ponds avant et arriere, indépendant de la boite de transfert ou boite tout court.. sa ce vend a monter d'ailleur, malheureusement on ne sais pas monter au dessus de 4,56:1 car le pond avant est trop petit, et mettre du 4,10:1 sur un 5 cylindre vas le rendre trop poussif par manque de couple a bas regime, pack off road ou pas je te rassure , donc avant ratio 4,56:1 arriere 4,56:1 , sur tu as le pack offroad tu as un blocage de "différentiel de pond ", fait gaffe c'est pas le meme pond que le mien ! Moi j'ai bien un 4,56:1 mais pas de lock differentiel pond

J'ai le blocage de pont arrière et blocage de pont avant.pack offroad.et je sais que le rapport de boite est plus court.
c'est pour ça que j'hésite.
t'es sûr à 100% ?
Tu vois,j'ai peur de casser,et une fois commandé, ...
merci de votre aide

Je comprens biensur, je wuis sur a 99 pourcent , de quelle année est ton h3t ?

Ici doc officielle au sujet du h3t... plutot rare

Je post le tout ca pourras  servir a d'autre

Et ils le confirme tu as un 3,7 tu est en 4,56:1

For posterity I think we should post up HUMMER H3T Test Drive Articles here to save them for the future CHOmies before the disappear into no where.

I'll start with this one from Rock Crawler Magazine: One of my favorite write ups on the H3T!

"OK, so you get it now. It’s a new pickup from the HUMMER gang. Just what everyone wants these days – another pickup. Big deal, right? Well, yeah, right!

When HUMMER slaps their name on something it needs to live up to a certain blood line – one that kicks ass and takes names. The H3 SUV already does that. We’d be happy to hit the trails in one any day. But how do you ensure that a pickup version can do the same?

Well, they took the project very seriously. HUMMER paid close attention to the details. For example, the spare tire had to be relocated underneath since the H3T has a tailgate. The engineers stared at it long enough to realize that it will get in the way off-road and drag. So they figured out a way to tuck it up at an angle, reducing the surface area likely to smack the ground.
5993

They also gave it a very complete set of skid plates and functional rocker guards so when the driver hears all that nasty banging, clanking and scraping underneath, they can shrug it off and keep on going down the trail.

The H3 SUV already had an electric locking differential in the rear. This year, both the H3 and the new H3T get an additional front locker when the Off-Road Adventure package is chosen. This package also gets the owner a 4.03:1 transfer case vs. the standard 2.64:1. Couple this to a 4.56 or 4.10 (Alpha) axle gear ratio and you’ve got one heck of a nice crawler right from the factory. The 5.3L, for example, would net a 50.6 crawl ratio (1st gear 3.06 x 4.03 t-case x 4.10 axle). Keep in mind that slow-poke I-5 H3T with 4.03 t-case would get a 69:1 crawl ratio! (1st gear manual 3.75 x 4.03 t-case x 4.56 axle).

Suspension consists of nice, flexy leaf springs in the rear and independent front suspension. Now let’s not get into the whole IFS argument here. IFS works great on the road and off-road it’s really coming of age.

5994

5995

While there’s lots to be said for keeping all four wheels on the ground (always a good thing), IFS is not the end of the world. The H3T gets plenty of droop and what it lacks in wheel-to-ground contact it makes up for with a great combination of lockers and traction control. It’s really really hard to get one of these things stuck unless you just plain bottom out on something. We tried!

All the traction doo-dads worked great. HUMMER had us on an off-road savvy press trip so they took us on a really nice trail which we all complimented them on. While many companies take you to a very controlled, just barely difficult trail so they can show you how well their vehicles work, these guys let us go to town on some real stuff. Yes, we actually had to use low-range the whole time and those lovely lockers were engaged plenty.

The H3T tackled it all with aplomb – it’s only real deficit being it’s length. We will say, though, that it had a very nice turning circle of 43.8’ – just a few inches more than the SUV version’s 37’. So we managed to get it through some pretty tight spots without having to back up and reposition ourselves.

5996

5997

Finally, HUMMER paid careful attention to the underside angles, so the H3T wouldn’t be it’s own worst enemy on the trails. With the optional 33” tires, approach angle is about 39 degrees, while breakover and departure angles come in at 20 and 31. Compare the breakover and departure to the H3 SUV’s 22 and 24 degrees. Not bad at all!

So who’s going to buy this thing? Oh, the list that comes to our minds is huge. Sure, there are the usual worker-bees – the construction guys, for example. But being in the Sierra mountains during forest fire season made me instantly think of the US Forestry Service or the park services. These guys have to get up the same trails that you and I like to go play on, right? Well, with an H3T, they could get their crew and all of their gear where they needed it easily – on or off-road. The same can be said for border patrols, road crews, etc.

5998

5999

But HUMMER’s money is on the weekend warriors and outdoors crowd. Their own lead designer fashioned the bed to hold his bikes for his weekend motocross events. With all of the different racks they plan on selling, carrying bikes, rafts, tents, ATVs or making those all-important trips to the local d-i-y warehouse will be a piece of cake, while coddling the whole family comfortably inside.

The HUMMER H3T has all the braun of a workaday pickup and the comfort of a well-endowed SUV. It looks awesome in person and oozes masculinity.

Unfortunately for GM, their timing couldn’t be worse to bring out a new truck. But for you adventure types out there who either want or actually need an extremely capable pickup and that Prius just won’t do the trick, the 2009 HUMMER H3T should definitely be on your short list when it hits the dealerships this fall.

Great looks, incredible functionality and kick-ass attitude earn the H3T huge marks from us. Bring it on!"

isoparme a écrit:Je comprens biensur, je wuis sur a 99 pourcent , de quelle année  est ton h3t ?

Fin 2009.

Merci de ton aide,Iso
t'es un pote

Maintenant que j'ai le ratio,
est ce que tout les ponts arrières de h3 et h3t ont un blocage de differentiel ?
ou juste les adventuur ?

Pour moi les adventur,je pense

Sur ton alpha,uu as les deux?

Et toi iso tu as quelle configuration?

Sur l'alpha j'ai bien le blocage de différentiel

Moi j'en ai pas

Ca dis quoi côté pieces tu trouve de quoi fait le devis a proposer a l'expert ?

Oui,mais j'ai du mal avec le pont.
c'est jamais indiqué si il y a le blocage de differentiel,
et les lames renforcées non plus.
si quelqu'un peut m'aider dans ma recherche.
c'est quand même malheureux que c'est moi qui doir chercher

De toutes les façons,avec les experts,tu as dans ton intérêt a blindé le devis car comme tu ne l'as pas expertisé,valeur argus,vétusté donc téléphones à Hummer France avec ton code VIN et tu auras un devis concret.

Je pense que Boul a raison, charge le devis

Mon carrossier a contacter le garage où je l'ai acheté.
Il a la licence gm pour le humvee cseries.

Si jamais vous avez des solutions,Tonny et jeanseb,

Appelles moi directement au tél.

Bonsoir Steph.
Tu en es ou avec ton Hummer ?

Salut Stef,

C'est vrai, on a plus de news!!! tu en es rendu où avec ton H???

Suis toujours à pied.
les pièces sont commandées et arrivent fin du mois.

Ah et bien c'est plutôt une bonne nouvelle tu as quand même avancé.
Je suis bien content pour toi, tant mieux

Tine nous au courant, puis si tu coince fait le savoir ! Tu as mon tel , si je sais t'aider je le ferais, tien bon il vas reprendre vie rapidement !
