Ram 4x4 Half Ton Rear Ends.

Anyone have any information or ideas how this rear end compares to others such as GM 10, 12, 14 bolt, Dana 30 , 44, 60, 70 as far as strength, durability and aftermarket parts? I've been looking thru 4x4 magazine advertisers for lockers and the such and cannot find anything for the Chrysler 9.25 rear end. I am not going to do any severe offroading ( rockcrawling etc..) it mostly is used in snow and mud at this time. It is a Chrysler 9.25 rear with the limited slip and 4.10's.

Thanks for any info.
