Yipes! I've seen front diffs like that, but that is the first rear case I've seen grenaded! I'm not aware of any aftermarket upgrades, but who knows, anything is possible. Not sure if a Wildcat rear diff would work, or if it is any better. They do offer a spike load dampener delete kit, but not sure this would prevent the diff failure. The damage looks like what happens when the pin weld breaks. AC had that problem on some early years. The fix was to check the factory weld, and then put a plate over the pin, and weld it on. Some of the broken cases were replaced under a warranty. I looked at the Arctic Cat Parts Store, and they show a complete rear for 850.00, I'd check with Babbitts Parts House, as they are usually cheaper. I spoke with several people on beefing up a stock rear end, and they all reported that the factory piece is pretty stout! I have a 700, and managed to build a complete case for around 350.00 dollars, but I had to search for the parts at a low cost, and it took several months to get everything I needed.
