yeah, this is for some JK Rubi 44's I bought back in spring.
I don't know if this kit would be ideal for use on any other axle, it seems pretty specific to the JK. You might be better off using the Clayton rear bracketry & truss, seems more "universal". you would then still need to figure out e-brakes & speedo/ABS for you specific axle. i believe tom woods can make a SYE kit for nearly anything, even the 242HD now that will have a speedo output so you don't have to use the tone rings, but you loose ABS.
overall I think the JK Rubi axles are a good deal for us even though they are priced a little high. i mean they are much stronger than what we have, good lockers, captive bearings, only slightly wider, same bolt pattern, working tone rings, easy e-brake setup, front/rear discs, and tons of aftermarket to make even stronger. i got flamed for saying that on Mallcrawling... the general consensus there seems to be that if you're going to bother swapping axles you need to be going to 60's or Sterlings and that JK's are overpriced weeklings.
