This has been posted before but I know how rarely stuff gets moved around for use as a reference so I'll repeat it again.MC = Duroflex, double adjustable, MC states they have more degree of flex
The claim of more flex is an attempt to prey yet again on the ignorance of the consumer by trying to make something seem important or valuable as a reason to sway one to make a purchase.
The TJ control arm mount is a fixed width. That doesn't change in stock form and rarely changes in custom applications. So, in order for a joint to achieve more misalignment you either have to make the mount wider or alter some aspect of joint. The rotational limit is controlled by the barrel of the joint hitting opposite corners against the inside of the mount sides.
Crudely illustrated thusly-
To increase the amount, either the barrel needs to get smaller in diameter or get narrower.
It isn't difficult to understand that either or both only take away from the amount of material that can be used for isolation inside the barrel. The better answer though is to understand what more misalignment does for you as the end user and that answer is absolutely nothing. You can't create enough travel with any length shock on a TJ that will even get close to using the misalignment available in most joints. If you can't get there, what good does any more do? The answer is simple, the claim is only there to prey on your ignorance since it has no actual realized benefit in real life. That and they lied about how much the JJ has unless they have corrected their BS since the last time I looked.
