Not sure about the time and effort for retrofitting junkyard parts, but quality stuff... yes I believe its a good upgrade. Everyone will say you could get a 44 for cheaper, blah blah blah, but not everyone is in the position to do that swap, and, a built 44 will cost just as much if not more. The XJ HP30 is a good axle, probably the most under-estimated axle out there. Lots of people are using the small Warn kit (myself included) with 35's and don't have a problem. With alloy shafts the hubs should be the weak link, which is good because it is a 5 minute trail fix, as long as you have a spare hub. If anything else breaks, you can unlock the hubs and drive home, fix whats broken in your driveway as opposed to on the trail.PizzaJeep said:is your time and effort to retrofit something like that on a already borderline strength dana 30 axle going to be worth it in advantages when your done?
