Bent Superior Super88 shaft - replacement options now that Superior is closed?

I bent my drivers side Super88 shaft on my last trip to Windrock. Runout is 0.060" at the outermost point on the face of the flange. This gives a nice little massage at highway speeds, and is very visible when watching the tire wobble back and forth. FYI, the shafts are 31 spline and I run 36" TSLs and a stock 4.0L. I never thought I'd come close to damaging these shafts, but that day is here.

I've come to find out that Superior is pretty much out of business, which is obviously a bad situation for what I thought would be a simple warranty replacement. So now I'm trying to figure out my options.

1) I'm told Yukon has an Ultimate 8.8 kit - does anyone have any idea if the shafts are interchangeable?

2) Bend the shaft back straight. This will obviously not be perfect, and I honestly don't know how possible it would be especially on my 20-ton shop press, but it's got to be worth a try. Maybe even worth finding a shop with a larger capacity press.

3) Any other suggestions? Thanks.

I'd rather avoid a custom axle since if anything happened to it I'd be in the same boat that I'm in now - no off-the-shelf replacement available.

Thanks to RWKHausSupply for contacting Yukon for more detailed info. Robert, would you mind me repeating here what they told you about their shaft?

After a little more digging, and finding the Yukon installation instructions, it appears that the Yukon kit is very similar to, if not the same as, the Superior kit.

All I can say is that the past Superior shafts were not in high supply, and superior was doing what they could to make up kits.

Yukon did base their kit off of the Superior kit, some say copy, some say reverse engineered, some call it making an competitive option. What ever you want to call it, Yukon shafts most likely will fit in to the Superior application without mod. But to this day Yukon can not say for sure, yet, if this is a 100% direct fitment.

I do have Yukon shafts available from their Ultimate 88 kit though, if anyone needs any.

An axle is a axle they all fit by length and spline, the custom axles I mentioned are stronger. I don't get what your issue is??

I've got a Yukon Ultimate 88 LH axle (and bearing, seal, etc) coming from a local club vendor. All indications are that it should swap back in, with my idea being that I'll have my bent Superior shaft with all the components on it as a trail spare. I'll update this thread with the results probably next weekend when I get a chance to work on it.

Right any axle for a 8.8 with the spl needed for that carrier will work with the pressed bearing, even a factory axle with that bearing and simple spacer will do the same thing. This isn't like having some discontinued part, superior copied a 8.8 axle without the C clip need and used a pressed bearing and lock and new retainer with seal.

My entire Superior shaft has a slight curve to it. So the whole shaft is bent, not the flange. I understand Superior didn't warranty bent flanges, so this would've been a good candidate for a warranty replacement

It's confirmed, the Yukon Ultimate 88 is a direct swap for the Superior Super88 kit. There are 2 differences I saw: 1) The shaft isn't coated black like the superior shaft was, so it'll get surface rust (I spray painted where it shows through the center of the wheel), and 2) the wheel studs are longer but don't prevent me from using my existing lug nuts. That's pretty much it.
