Hey guys, I hope this is in the right section. I'm still learning the forums and where to put certain things. Anyways, I got my '93 2WD XJ that I'm doing a 4x4 conversion on, soon as I get a transmission. I planned on just putting my HP30 front axle in it and running 31's with a 3 inch Rough Country lift. I got a 8.25 27 spline in the rear already running 3.55's. Should I just throw the HP30 in it and run the 8.25, or go ahead and upgrade both axles to something else? This will be my DD and my trail rig, so I planned to really fix it up down the road a ways, but got to thinking if it'd make more sense to go ahead and upgrade, rather than install a new axle, then down the road basically re-do everything. Thanks guys!

 

Upgrade your rear axle by replacing the shafts with 29 spline shafts and a corresponding carrier.

 

Awesome, thanks!

 

Unless you go 35s or bigger or break stuff left and right upgrade the axles you have and your good to go.

 

X2 you should be good to go.
