Portal axles are an interesting concept - they will lift your differentials 4" without touching the rest of the suspension- but I would worry about durability. And at $5,000 per corner, just a touch pricy...

Haven’t watched the video but portals are very nice. Would be nice to see a factory option… there was a hot second that mopar offered them.

How much more stress is placed on the control arms with that much more leverage from the portals?

Lifting your differentials 4" would be like running an 8" taller tire.

As far as durability, 74WELD portals have some serious off road racing experience behind them:









I would not put them on D44's. For $25K, I would do a complete set of Ultra 70 portals from https://www.dstracaxles.com/collections/jeep-jl
The nice thing about portals is they take load off the upstream drivetrain, so you don't have to run big axles.

Is there a part number?
This portal setup is how the Humvees work.

So the rig in the video has stock axles with only portals added?
I don't know about the rig in the video you're mentioning. But I did just get a text from Quinn at 74WELD, he runs a Teraflex 44 front and a CRD60 rear under his JL 392 with 40s.

Portals are really cool, and function well, but for most use cases they're usually too heavy and expensive to make sense. The regearing at the hub does take strain off some of the upstream drivetrain.

Mopar did offer them ~2012-13.

Unimogs and Pinzgauers use them on most configurations.

I'm waiting for someone on here to buy these and wheel 39's with a stock axle and suspension setup.. If I was a rich man I'd really consider them. Having a shop throw on a lift kit + bigger brakes + regearing adds up for sure. I don't think to $25k but still...

They're claiming that the leverage an axle experiences with portals and big tires would not be much more than without portals (with correctly offset wheels for each respectively). Since the portals push the hubs out a few inches, you can get away with a higher backspaced wheel (like 6" or so) for something like 40's. Where as without portals, you'd need 4.5 of backspace or less to clear that big of a tire. The wheel backspacing evens out with the added leverage of the portals. Whether that's 100% true or not I don't know, but this diagram looks believable..

Hey guys. You think the sport dana30 on 40s + portals would hold up?
Lol do you think they'd hold up without portals?
