I just checked their site and I see they are now offering "stock" UCAs which Marlin had told me they had no plans to do. So I would think you want "lifted" arms for 2"-3" BB, and "stock"UCAs arms for a SuperLift. But if you go with the JBA 6" or a modified SL then you want "lifted"arms arms.

Yea I'm planning on modding the SL to about 5" of lift, I think I'll have to stick with the stock ones I have now and then later on down the road pick up some "lifted" ones. Thanks for the info!

I run the RRO's, and have seen the JBA's. They are not a direct copy, they are longer than the original JBA's, different shape on the arms etc. No more of a copy than any aftermarket one is of the factory.....

The New JBA arms and RRO's are better for 2-3" lifts and 5-8" lifts. The early JBA's really only suit the JBA coilovers. For a straight SL of 4" with no coil change in the front the JBA "stock" length Upper arms are best. You can use the RRO's and longer JBA's but you need to modify your tierods to get more adjustment to get proper alignment. Simple fix though.

I have had no issues with the RRO's bushes as yet. But my Jeep only gets wheeled most weekends, doesnt do alot of city miles.

Both are very good for the purpose. JBA's list of goodies for the WK is extensive, so thats always a good thing to think about.

As I understand it, the RRO arms are an exact copy of the first JBA arms (3 revisions ago). After RRO started selling them JBA redesigned the UCA and flipped the BJ around as well as beefing up the bushings. JBA continues to refine and improve their products based on customer feedback.(hence the many revisions). I have never heard anything good about RRO customer service.

Also, while I was testing the "lifted" arms alot of people asked about "Stock" height arms. When I mentioned it to Marlin he said they had no plans to make them unless there was demand. I told people to E-mail JBA directly if they are interested and sure enough, when I checked their site yesterday they were offering "stock" arms.

I worked with JBA on the most recent UCA design and I have to say they are awsesome to deal with. Very friendly and knowledgable.

What advantage is there to using the arms designed for a lift vs stock? At the moment, I'm lifted and still using the stock arms without issue

The advantage is that the JBA has grease fitting on the ball joints where as the stock are not serviceable, the BJ are stronger and replaceable, and the arms are angled so the BJ is is in the proper position.

Well the current RRO arms are not a copy. You're saying you heard they are a copy of the original a few revisions ago, but really if you don't know it to be true then why keep repeating it. I had no issue contacting or working with RRO so unless you have personal experience with them or can say for sure they are just copying JBAs work then what's the point?

The info is direct from the source. No hearsay. Many people on this forum are familiar with the RRO business model. I'm not stating anything that isn't already known.

RRO current UCAs are the same as JBA from 4 or 5 years ago.

If you read most of my posts you'll see that I usually don't respond unless I have some information to pass on. The OP is asking why JBA is more expensive then RRO, I'm simply explaining why - R&D costs money, as does re-tooling for revisions to existing products. I have never purchased from RRO simply because of their reputation(on this and other forums). I have worked with JBA though and can confirm they are a great company. Since I helped with the R&D of the new UCA I think I'm probably in a better position then most to chime in on the subject. (They fabricated 4 sets of UCAs for me to test, plus the final painted product. That's alot of time and money to improve an existing product)

Also, prior to my purchasing JBA UCAs, I did not know Marlin and had never purchased from them. I was a first time customer who contacted them because I was unhappy with the fit and thought there was room for improvement. Most companies would have responded: "Thank you, we'll pass that along" and then offered a refund. Whereas JBA rose to the challenge.

Not going to argue with you Budasac, i do agree on the development and ongoing other products which i mentioned in my post.

When i bought my RRO's, the JBA arms at the time (whatever model that was) sat the knuckle closer to the coil and limited travel with factory style coils compared to the RRO's.

As for customer service, my RRO's arrived 6 days from order, but did take around 3 weeks to get into contact with. I never got a reply from JBA. But as my best mate down here is now a dealer for them it wont be an issue!

I think there is now around 6 threads just on here about these arms, ill bow out gracefully and leave the arguments to others.

No argument here. Just trying to inform others of what I have found so they can make an informed decision when spending $400+. My original arms from JBA rubbed as well, which was what originally started the revision on the newest arms. The JBA v1 (RRO arms) I think were a good fit, but in their haste to revise them so they were different then RRO they took a step back on fit while stepping up on durability. Those are the arms that alot of people had rubbing issues with. One problem is that both the XK and WK that they have to work with have 6" lifts, and while they fit fine on those rigs, people with the more common 2"-3" lift had issues, as well as SL rigs which are designed to use stock arms. I think now that the arms are dialed in better to fit an OME or BB as well as a 6", and the addition of stock replacement arms, JBA has all the bases covered.

As far as comparing the current JBA arms to the RRO arms, the biggest difference would be the bushings, as RRO uses KK bushings. I would assume the BJ is the same. (Just turned 180 degrees). I believe they are Hummer BJs.

As I stated, I have never dealt with RRO, I know them by reputation only. Marlin and JBA I can personally vouch for though. To be honest I was leery of both companies. RRO for their CS reputation and JBA for pushing religion (Marlin sends a "Life of Jesus" dvd with all orders). I'm agnostic, but I needed new UCAs, so here we are.
