I like the fact that they are innovating and doing something different than just ripping off JJs.
You're right, at least they're trying to do something different. If you want to test them out on your Jeep, more power to you. Me, I prefer to use what has been thoroughly tested, proven to be the best for 20+ years and used on Ultra4 race rigs. Of course, that's just me.
Their arm geometry is interesting as well....
Ummm, yeah, I don't think so. That illustration is imaginative at best and designed to sell an idea to suckers who don't know any better. If nothing else, the Full-Traction arm uses an FK rod end which is essentially a uniball and there is NO other joint available that offers a greater degree of rotation and 100% bind free. To suggest otherwise is just disingenuous and it alone should discredit what is trying to be sold here.
Sorry, the concept behind the MC flex joints is interesting but I personally have worked with them and can tell you that they do require a degree of effort in order to rotate them in their joint. If decreasing bind is the only thing you're concerned with, a uniball is what you'd want. Of course, the down side to that is that uniballs offer no absorption and that's why they are typically found only on race rigs or on control arms that have a rubber or polyurethane bushing on the opposite end. Now, a Johnny Joint will not have ANY bind until it reaches it's limit and unless you have more flex than this, I can guarantee you that you'll NEVER reach that limit.
BTW, the only thing limiting our flex in the photo above are the limiting straps we have installed to prevent drive line bind.
The question is, will their bushing truly hold up (which it seems they are) to many years without needing to be rebuilt. Not to mention they are almost zero-maintenance. They have my attention at least.
Ummm, not exactly. They are working on it but this is what people were seeing early on...
Granted, they have since made improvements but, here's what their zero maintenance joints will look like after a while.
That being said, I'm all for folks like you spending your hard earned money to test out new products. I mean, someone's gotta do it. :yup:
