So i painted all of the links and axles today. While I was out there I was thinking about how much beef I should put in the axles. If I get the 35 spline upgrade kit for the front with 4wd factory drive flanges, yukon greasable u-joints, and yukon 1541h outers..and then get dutchman custom alloy 30 spline shafts for the rear will I be alright? I don't wanna be afraid to get it a little bit, in fear of breaking. I will be running 5.38's, spool rear, arb front and I am only on 40's.
