DANA Ultimate UD60 TORTURE TESTED & PROVEN on the JL / JT Experience

LOL - seeing is believing. Of course, this is to say nothing about how they're hard to balance, have tread cupping issues and wear out quickly.

It’s kinda like buying a lottery ticket, you might get a few that balance with 2-4 ounces then you might get a few that balance at 15-25 ounces. And if you’re really having a lucky day you might get 3 out of 5 that are actually round and will pass road force. Isn’t that how it should be? [emoji13][emoji51] I’m sadly speaking from experience. But hey, at least I can give a true I bought them with my hard earned cash review vs most of the persuasive views out there on the internet!

Yup, that's about as honest as it gets. Mel has a customer that came in while we were there and he said he had the same problems as you. He literallyhad to have 3 tires replaced and right from the get go because of how they wouldn't balance worth anything. On multiple occasions, I've personally seen where only 1 of the 4 tires on a Jeep were wearing like shit. I just don't know how "influencers" can be pimping these tires with a straight face.

At about 13:00 minutes in on this video, you can really see Skyjacker punishing his Dana UD60 axles and Hellcat HEMI. You can actually see the fronts wiggling as they grab traction from time to time.

Again, the whole point of us testing out a set of Dana Ultimate UD60 axles is to see how they'd hold up to the kind of abuse we'd put them through. I think our videos speak for themselves.

I had saw that, crazy. If they can handle all that horsepower, that’s a huge testimonial to how well they are built. If only he had traction!

LOL!! If Lonnie had traction, he wouldn't have needed to spin up his tires as much as he had. :crazyeyes:

After spinning those tires as much as they did, I’m sure traction was better for the guy behind him with all that melted and chunked rubber all over the rocks 🤣

:cheesy: Too funny but you could be right.

Looked to me like a few of those axles took direct hits to the diff as well with no hint of damage.

Oh yeah, crazy hard hits and we purposefully put those clips in to show just how well they took the abuse. :yup:
 
Have you ever rebuilt RCV shafts? I watched the videos and it looks like a giant pain in the ass. Still, I may do it over Winter just to quiet the damn things down.

Ya I just rebuilt mine. It was way easier than I thought it would be. Only took about 5 minutes per side once they were out.

I've never had RCVs but they look similar to the Birfield joints on old Toyotas. The factory ones sucked, but had a long life.
The outer shell was thin and weak.

Bobby Long made Longfields, which were nearly indestructible. When he passed, I heard that RCV took over his work.

The main design point was making the balls smaller so the outer shell as well as the inner race were able to be made thicker. That, as well as using 300M material and a cryogenic treatment, made them much stronger. The downside was the faster wear on the balls, which leads to the clicking.

They are only hard to take apart the first time. After the first one, they are pretty easy to rebuild. A BFH helps too.

I've run RCV in the past and I'm running them now on my JL because it was the only option available for my PR44 but for the $400 premium, I'm still not a fan. I've been running chromoly shafts with full circle clips for 2 decades and have never had to deal with the snap crackle and popping that you get with RCV's and they've always been just as strong. Well, for me anyway. Granted, I'm just a mall crawler so there's that.
