what the heck should i do to upgrade this axle.  It is a bit of a dog when it comes to finding parts or upgrades.  I do believe that it has the lsd, but that is like putting a button in ur pocket and running into a gunfight. Thanks for any replies.

power-trax, makes a ratchet-style locker to replace spider gearsin the lsd, but I never found any other, unless you go with a full locker. gears you can only find up to 4.56. This is all I know from looking my self.  

I f yo swap in an open carrier, yo can get a bunch of differant brands of quick locks. Aussie locker is the cheapest I found, but they dont make it for the lsd.  

What do you do with the veh? If its just for wheeling than weld rear diff. unless you want lower than 4.56 then swapp with ford 8.8  

There are two 8.25 series axles. up thru 96 the axles were 27 spline. In 97 they increased axle size a bit and upgraded to 29 spline too. It is not a weak rear axle and I would place it above a D35. They also make a gear based True Trax LSD unit for that axle. (no clutches to wear out)  

If your jeep will be wheeled hard and driven on the highway, stay away from c-clip axles all together. It's easier to buy into a aftermarket upgrade axle than to bandaid the original.  

byt the price is a little steeper
