I am drawing a blank of this other axle i saw. its a solid axle but has CVs or U joints in it. it raises the Diff in the center but its all surrounded by a solid housing?

 

those knuckles are freakin sweet!

 

i know the axle you are talking about, its Rediculously expensive cause it has 8 or so Cv joints in it. it Uses a 9" center with some dumb looking axle housing. Your better off running a Mog or volvo axle as they are stronger for that price.

 

yeah but it would fix this argument about ground clearance now wouldnt it?

 

i meant to mention Portal Axles in my first post, guess i forgot.. reguarless, show me an IFS/IRS truck that will do something like that rubi did in the video and ill be impressed

 

nah cause it doesnt have as good clearance as a portal, and just marginally better then a regular SA

 

That s10 buggy ran that suspension for only a few competitions that season. After it ran a couple they didnt like it, and it was choped off for front and rear SA's

 

I am not going to knock your theory, but all I am going to say is look at a Solid axle swap Ranger, or a Jeep Wrangler (2006 and older) vs a stock or even LIFTED 4x4 IFS Ranger. There is NO COMPARISON. Solid axle wins EVERYTIME off road. IFS was made so people would have a softer ride on the solid pavement, but they sacrificed articulation and rigidity of the axle not to mention several other things. If you want a off-raod truck that can keep up with those jeep guys, you need a SAS.

 

Kids, think of a military Humer. It is a very capable off-road vehicle. It has 4wheel independant suspension. Yes, the differentials are higher up along with the drive shafts/ transmission/transfercase. But yes, straight axle has it's advatages. But there is no reason to get all hurt there Aaron Bruce. If he doesn't know then educate him.

 

Hummer is special though. It combines Portal technology with IFS, thats why it has so much ground clearance.

 

Like I said earlier, stock vs stock SA will normaly be better. Even mild-extreme offroad vehicles SA is better. SA works better because as one wheel in hitting a rock it smashing the other wheel into the ground which in turn is more traction.

Now when I say IRS set up I am thinking full custom crazy machine. Sway bars could help push down the other tires when flexing to help with traction.

I know if IRS was better more people would be running it. I am NOT SAYING IRS OR IFS is better at rock crawling. It was just a idea. I gave some points and I am wrong.

But like i also said the smaller vehicles (even rock crawlers) have IRS so maybe IRS or IFS can not be utilitzed as well on a bigger vehicle.

The hummer 1 is a good off road vehicle, but I have yet to see one rock crawling.

Rock crawling = SA
Bumpy terrain = IS IMO
Fast off roading = IFS, SA or IRS is a godo choice.

but I still think someday a all out IS machine will be utilized. But you gatta agree a good IRS/IFS set up will have more groudn clearance

 

Yes... It is an H1, Not a Pu55ified H2 or Soccer Mom H3! It was made for the military for indigenous terrain!

 

Ok, here's education.

UNIMOG AXLES ARE THE ****! Live em, Learn em, Love Em! Nothing Beats them! That is how the Hummer H1 does what it can does with IFS / IRS. The UNIMOG Axles give it the STRENGTH of Solid Axles with the Clearance to boot!

 

aaron already explained this, the first bump you hit you lose all that clearance

 

you mean portals, unimog is just a company that uses a portal design. the h1 does not use unimog axles.

 

I have seen 3 ifs or irs crawler rigs in my life time. I know two of them that cut off the IS for SA's. that little blue buggy posted earlyer wasnt a crawler, its a 2wd buggy.

 

I know but there is some UTVs like the rhino and stuff they built for rock crawling.


But yes After reading I see why SA is on top.
