Both the 8.25 and 8.8 are shitty c clip junkyard axles.
The only advantages to them is that they are cheap, and readily available compared to a 44. The reason they are cheap and readily available is because jeep guys are the only people that use them, and again, thats because jeep people are cheap to a fault.
8.25's are a pain set up, and have limited gearing selection.
8.8's have weak outer flanges that are prone to bending, are to narrow, and require that the ring gear to be shaved when installing anything deeper then 4.56 gears. 8.8 stock carriers have notoriously bad spider gears that are prone to blowing out. The LSD in a 8.8 is a standard clutch type, and a peice crap among every other OEM LSD thats been put out besides the LSD associated with the rubicon rear truloc.
Ring and pinion and axle strength comparisons between 8.8's, 8.25's, and d44's is irrelevant. None of them blow up on a regular basis.
The d44 is a better rear axle in regards to service, aftermarket support, clearence, and weight. The only downside is that its slightly more expensive.
But, by the time you get a 8.8 into a TJ with the proper bracketry and address the weak stock carrier, and do a super 88 kit to address the weak stock flanges and get rid of the c-clips..............................You've spent just as much money as a good TJ 44 would have run you.
If you dont ever plan on more then 35 inch tires for quite some time, I would simple do a superior c-clip eliminator and truss combonation on your existing 35 and wheel it.
One of the most aggressive wheelers on this board has been trying to break a 27 spline superior c-clip eliminator for over a year now with no luck.
I also have a guy out there on 35's and beadlocks with a super 35 eliminator and truss that has run some of the toughest trails in mclean with no issues.
My wife ran a trussed super 35 for nearly 4 years before we finally took out the locker in a rock crawling competition.
Be carefull what you beleive when reading internet spam. Most people just pimp the crap they run, or the crap they've read about and wish they were running.
