Johnny Joints vs. Metal Cloak Duroflex Joint

Any trail proven advantage to metal cloaks joint. I invested my control arm upgrades before MC Duroflex came out.(are they even out with a tj application) I bought Rokmen arms and am happy so far. Besides recentering the joint what do you guys see the advantages as...

I just watched their vid:


They seem like a good thing, but until someone buys them and abuses them we won't really know.

too new to know the weak links on them or if they have any real benfits over the currie joint. right now I'm not trading in the curries or ruff stuff rod ends for them.

Nice vid. I see the center tearing out of the rubber, or grit getting in between the arm and the rubber making a greasy sandpaper and the joint getting sloppy fast. Might work good for a bit but I don't see the centers lasting long. At least they are easy to rebuild!

From Metal Cloaks own video dual MC bushings will allow a control arm to flex/twist 34 degrees. Currie Johnny Joints flex 30 degrees each joint, so dual JJ's would allow a control arm to flex/twist 60 degrees.

Also it looked really easy to install the c-clip into the MC joint, leading me to assume that they won't have very good side load resistance.

Cool idea but it doesn't take much of an imagination to realize why JJ's are better.

Well after about 14 pages of that thread I lost interest. They do not seem to be competing with the JJ. They seem to be competing with Clevite. Nuff said.

The video shows them competing with both. Just saying.

I don't have a lot of faith in that rubber not breaking away. It'll be interesting to see what happens in real world abuse, over time. Seems like a neat idea.

I tried reading the thread Imped linked, but I got lost/bored too. I'm not sure if there was something posted in there by the OP that said whether he liked them or not.

Currie JJ's work well, are durable, cheap to repair. What more does one need?
I see no reason to try and invest in a better mouse trap, when the proven stuff works extremely well and is a proven durable part. Just saying

I know I really loved the way my Rubi performed last time out, which was the first time out with the Rokmen CA's with JJ's.

I'd like to see how they last in the long run for a DD it's hard to beat the low maintenance, but for weekend warriors and extreme rigs ????

If they hold up i would consider them an upgrade from JJs, unfortunatly I don't see that happening. That is quite the duty cycle for rubber.

In what way would you consider them an upgrade to a Johnny Joint and why?

Great thread... thanks for posting the question...

For our application, we are not trying to compete with the JJ. What we've found after over 10,000 miles of testing on our Red Rubi JK (Cloak 3) on both trails like the Rubicon, Death Valley, Ocotillo Wells, all over Moab, and thousands of Freeway miles is a Jeep that still rides like its brand new, with no visible signs of wear on the joints.

Our target market is the guy who wants to have a high quality ride in his DD while being able to flex with the best of them on the trail.

Thanks for the kudos on the vid. As for the center tearing out, our own testing took 5000 lbs to break the center from the rubber. And even then it broke the rubber, not the vulcanization of the steel to the natural rubber.

So far our customer base is liking the ride-ability of our overall suspension system with the Dual Rate Coils and the Duroflex joints over some other suspension options.

However, we recognize the preference that many have and the dominance that the JJ has seen in the marketplace. We hope we can continue to grow and provide more and more feedback on the various rigs that have been built with the Duroflex.

Feel free to pepper me with any questions you may have.



BTW, that thread mentioned before is definitely a primer on suspensions in general if you can get through all the craziness. (and yes the OP does provide feedback on his MC experience.)

dude really? Stop sucking Curries d***. Whats wrong with somebody running the new metalcloack joints?

Are you always gonna compare everything to JJ? Are you gonna start telling me that heims are bad to run?

I started out with bushings on my XJ arms and they worked fine. Not everybody needs JJ's, so stop making it sound like if you dont run JJ's then you shouldnt ever wheel your Jeep, or that your jeep is far less capable.
