Jaxon1023 I'm a mall crawler such just a tall jeep. I'm 38 years old and know all about the pros and cons and always wear my flame suit when coming onto forums lol. Ultimate goal may possibly be 38's so just don't want to have to buy 4 control arms all over again.

By "these" you mean which in particular?

6" of lift on most any of these short arms is a bit much, though not saying it isn't possible. What are you trying to do that warrants that much?

Other than that aspect, they aren't worth any more or less than any other arm.
This is exactly why I asked this question. The convenience factor for now and future mods seems to be worth the extra cost (if any).

Figure out what joint you want and go from there; the rest really doesn't matter as it's hard to screw it up.

I'm running Savvy's aluminum double adjustable arms myself and am very happy.

There have supposedly been some actual long term reviews on some of the JK forums, but even still the joints are relatively new and who knows what kind of abuse those people put the joints through.

But regardless of all this, the main question asked was about double or single adjustable arms. I'd take double adjustable over single any day of the week. Some will argue you only set your pinion angle one or two times and never touch it again, but for me that hasn't been the case. I've done things in stages, and have adjusted my pinion angle more times than I could keep track of. Having double adjustable arms makes this very quick and simple to do.
I completely agree

With out a doubt. The people that say "you only set pinion angle once" must have completed their builds all in one shot. Even adding a 100lbs spare tire and carrier can change the PA as ride height changes.

The self centering ability is pretty much useless. The only time that is useful is if you have bent arms that need to stay centered. Otherwise, it's just a pointless marketing ploy.

It's not that it cannot articulate, even a rubber oem bushing can articulate. The problem is you are asking the bushing material to deflect to do it. That will cause wear. WIth the JJ, the urethane cups that act as the bearing race, do not deflect. They simply capture the center ball, which is free to rotate on its own. This means the only wear you are getting is from the ball moving on the cup, and with the new chemically polished center balls and a periodic application of grease, a sett of JJs will outlast your jeep, all other factors remaining the same.

I'm sure the duroflex joints will last longer than a bushing, but not nearly as long as a JJ.

Also, any material they are using with a low enough durometer to allow the deflection needed to get the 34 degrees of misalignment they are claiming is going to be soft enough to give the same kind of loose suspension feel as the oem bushings.

Their only real argument for these bushings is that they eliminate more NVH than a JJ. Regardless of whether or not that is true, although I doubt it, it's not going to be enough to matter. I repeatedly switch back and forth between a lifted rig running JJs on all the CAs and a completely stock jeep using stock rubber bushings, there is no noticeable change in NVH between the two.

Having had about 30-40k miles of street time and probably 50 or more trail days on a set of JJs with no noticeable wear, and no noticeable change in NVH from them to an oem jeep bushing, I would never waste my time with these.

They are designed for mall crawlers.

They replaced the best part of the JJ, the center ball and replaced it with the worst part of a bushing, the bonded sleeve.

geiman I would have no problem running the Duroflex on my rig, but that being said I would have a little more faith if Metalcloak themselves would run them on their own KoH rig.

I haven't seen any accounts of the joints wearing out so you can't really complain much about them yet, but you would think if you had a hot new joint out you would throw it into whatever destructive testing you could find to see how tough it really is.

I'll stick with my JJs though; no issues whatsoever with them, and you don't have the "mystery" surrounding them like you do with the Duroflex joints since they're much more proven.

elclipo I can see the advantage of the dual adjustment. I have also seen great reviews about the dutaflex providing a superior ride both on and off road. I haven't had the luxury of anything but stock, and would like to only make the one purchase and be done for good.

The double adjustable feature is just gravy that makes install and pinion adjustment so much more awesome.
05-06-2013 04:37 PM
Big Cole Adjusting pinion angle without having to remove the arms from your rig is a great feature. I have no complaints with my savvy arms

Single side vs. dual side adjustable CA

I am wanting (needing) to get new arms and was set on Savvy's set until I saw the Metalcloaks and their duroflex joint. However, the savvy set is adjustable on both ends while the metalcloak is not.

Any real advantages/disadvantages to having a dual setup versus a single setup? I would think the dual setup is the way to go but I'm torn between that and what seems to be the better joint.
