Triple88a Hackle, i gues because you need some hard bracing to hold them up?

Hackle A couple years ago all the Competive Rock Crawling crowd loved the portals due to clearance gains. Now hardly no one runs them! Great clearance but they do not hold up to the level the competion requires.

page 2-3 is where it starts getting alive

So far i've found that a portal axle is suppose to be much stronger than regular axle.. D44 is suppose to be stronger than regular D60.. The reason for that is it takes the pressure off the rest of the drive train.

Triple88a Wow thats exciting, if that comes through at affordable price this would bring a whole new meaning to re-gearing... regearing + gaining clearance.

Rawkon theres different model of portals too. 404 and 406s i believe. the 406 or more desirable because you can take them at freeway speeds safely. something about the 404s you have to stay under a certain MPH or they will overheat.

i dont see anything wrong with converting them to use with a 30 44 combo as long as you truss the axle and beef up the internals and do something about the axle wrap they usually cause. my brother in law is putting them under his dodge ram. he has the rear done already but the front is taking forever due to his lack of motivation and laziness.
those are tough axles with boat loads of clearance.

now i have never dealt with them personally but the info i posted is from what i've read and have seen

rebelBullDawg325 we were talkin about portal axles in a general truck forum i'm in the other day and i remembered this thread. so i mentioned these conversions or whatever and said i'd post the link. but the link is now dead. anyone know a different link that works?

Scoob I have seen portals and played with them on a jeep.

I would not want them on a daily driver. I don't know if they could handle the strain of 70 mph and they would be noisy. However I have never seen them on a Jeep that was anything other then a trailer queen. So that is just speculation on my part.

debruins good point digger, if you break your axle because o fthe portals will they replace it/ fix it/ put i tback to stock?

something to think about

Digger 5 Portals are a great IDEA for Jeeps. You gain ground and tire clearance without a lift. You get gear reduction in the portals that removes stress from your axle shafts. In theory, you could use 35" tires and get ground clearance equal to using a 40". Large tires have some huge advantages (and disadvantages) that won't all be covered by using a portal. The ground clearance gained without hitting the frame (when turning) with a really large tire is a great idea.
The part that concerns me is how to make the attachment point for the portal withstand the leverage that comes with lowering the tire centerline. We all know that the TJ Dana 30 C is weak, as are the tubes of the 44 rear. Can these parts withstand the torque? Even trussed? What happens if this doesn't work out? Will the company pay you to get the rig back to stock?
I like the idea. Done right and mass produced (for the right price), it could be a revolutionary change in wheelin'.
I don't think I'd like to be the first on my block to have it. I'll stick with my ProRocks.

Walkeraviator I see. It kinda works like a planetary gear system. With the shaft as the top gear and the wheel as the ring gear.

Walkeraviator OK time for "answering stupid newbie questions." I know what a Unimog (vehicle) is. BUt someone explain to me what the heck you are all talking about? What is a Portal? Im lost but I am always wanting to learn a little more.
07-26-2007 11:11 AM
Vector6 I must have missed my PM with pricing...
07-25-2007 09:50 PM
debruins what about if you trussed it, or am i thinking about a different problem?
07-25-2007 09:46 PM
1BLKJP Portals have their own problems. I wouldn't trust the tubes on a 30 or 44 to hold the forces of a 38" tire. Hell I've seen guys bend 30 tubes on 35's.

Not saying it can't be done because everything can be done. But you can't expect to do something half assed and get a good result out of it. My feeling is they brake and they brake badly.
07-25-2007 09:12 PM
debruins looks pretty cool
07-25-2007 09:04 PM
Scoob Unimog axles in a Jeep..no way

A guy in our club...we have been working on it for a couple months now...Just about ready to go.

4Jeepn My only concern would be support after the sale...
07-25-2007 08:11 PM
nicolas-eric i sent you a PM. don´t want to talk about prices of a non-released product in the forum where all the world can read it.

i couldn´t believe it.

the owner of that company has a street legal CJ and YJ with portal axles and 38.5s...
07-25-2007 07:59 PM
debruins well how much are we still talkin here for half price?
and for how long is he gonna use your jeep, 2 yrs? 10 yrs?, is it even legal in germany with all the laws,
you also understand that even with the axle ratio you are still gonna lose a lot of performance
also remember that buying 38" tires isn't cheap either!
but if it inst gonna be more than 5K for both then i would do it

a buddy that moved to the US some years ago and founded an offroad company in colorado springs will have this kit.
it will be available for D30/D35 and D44 axles. you only have to install the portals and not to change the whole axle.
installing unimog axles is very hard. you need to shorten them because stock unimog axles stick out about 15-25" on every side of a TJ.
