Currie/JKS/RE Control Arms?

Looking to buy a set of adjustable rear upper CA's to install with my new CV shaft. I've been comparing the Currie Johnnie Joint ($340), JKS J-Axis ($310) and RE Superflex ($240). The only major difference I can see is the Curries have joints at both ends while the JKS/RE have bushings on one end and joints at the other. Are there any other major differences? I had the RE's on my previous TJ and never had an issue with them, any reason to pony up the extra $70-100 for the Curries or JKS?

The design and quality of the joints themselves is very different. I will never install an arm with anything but a real JJ in it.

Can you elaborate a bit on the design differences/issues presented by each? This jeep is mainly my DD and only sees mild/moderate wheeling once a month or so. Are the differences most apparent offroad or under normal driving?

I never had any issues with the RE superflex joints, but the crappy design of the hourglass rubber bushing meant I had to replace them every 5k miles. I had an older RE lift on my XJ that never had any issues when they used to use the OEM style rubber bushings, but they really went downhill with the newer bushing design. I ended up replacing all 8 of my RE arms with Rokmen arms. They use Currie Johnny joints on both ends, just like the Currie arms, but at the time were a little less expensive.

no problems with my RE superflex arms on 2 jeeps. Both jeeps were only driven to trails and wheeled almost every weekend. Never an issue, every so often just have to tighten the Flex joints.

You are going to get a mix of opinions on what to get. If what you have been using in the past has worked, why change , if not needed.

jks arms are a gimmick that dont allow lateral movement and use rubber bushings
RE arms use rubber bushings

currie/savvy/MC and several others use quality joints that dont require regular maintenance or replacement while allowing the maximum amount of rotation.

JJs don't require maintenance...first I have heard of that. I should get these magical bushings!

They need a squirt of grease every so often. That's it. However, if you neglect them, they still function fine with no damage, just a little squeaky until you grease them again.

So they never get loose ? Wear out ? They just last FOREVER?

Thanks

It takes a long time. There are arms on mine that are close to 10 years old and they've gotten a shot of grease maybe once or twice a year. Still as tight as the day they were installed as far as I can tell. Only joints I have had any detectable wear on have been the axle side front uppers. Any amount of DW or even out of balance tires can be very hard on them.

thanks Biff.

I have heard otherwise locally here. That's why I asked. Obviously different environments/climate may dictate life of the bushing.

Not significantly, mine get used in as harsh of an environment as anyone's do. Dry dirty rocky trails. Mine are 12 years old and still tight, I have greased them maybe twice. Those who disagree are those who don't own them, they're just repeating what they read on the intraweb.

Gone to Florida 7/19-7/28.
When you have a choice, buy American made.

Yeah my experience isn't personally on my rig (as I didn't like the ride and got something different). This is from 2 of my wheeling buddies who wheel hard.

I will definitely say your environment is ALOT different than us up here in the Rainforest. Not sure how you can say yours is the harshest environments lol... You see dry weather almost year round , where we see 8months of RAIN. This leads to wet, muddy, trails for almost all year round. That will affect the life of ANY bushing significantly.
