    Hey Guys, I’m curious to the pros and cons of the Jba 4 link vs IRO wj rear a arm. Has anyone tried both and what are your experience. How is handling and noise?

    Both about the same as far as handling, I run the JBAs on my 03 and 04 , some complain about noise, but if you clean them and spray them with lube every now again no noise at all
    I have about 75-80,000 on one set, 50,000 on the other
    But JBA is no longer available so guess what is left, yep, trying to find someone to make the bracket for the IRO, good luck

    thanks Tom. JBA has one more of the bolt on and I found a guy making the mount. Debating which one to go with. Do you have the bolt on or the welded version?

    Bolt on, have the very first preproduction one on the 04, was a tester, test did so well still one there
    compare prices of everything
    last I saw one guy making the brackets he wanted arm and a leg, then had to buy the IRO on top of that

    The guy who made them told me $170 shipped. I’ll have to call IRO and see how much they can do the a arm since I don’t need the bracket.

    There's a number of simple truss options for well under $170.

    Has anyone inquired if IRO will sell the truss part off their WJ axle swap bracket kit together with the arm?

    The IRO arm comes with WJ bracket. Its a flat 3-bolt top-mount that would be easy to re-create on a truss.

    Oh look. ECGS figured it out

    Yeah he’s the one who quoted me $170. It’s a bolt on bracket not a truss

    No. After some mock-up, the only part that plays nice is the upper mount and arm.


    Yes, the truss IRO puts in their axle swap kit is weld-on....
