yeah man welded diffs don't ruin anything if done right. Ive welded like 20 haha drift cars millions of toyota diffs 1 tons anything haha none have broken. But either way some thing come from a spool. Im "spooled" front and rear haha welded that is and not troubles I rarely drive mine on the road. I personally see nothing bad from them is less shock load on parts as to where a locker is popping and ingaging disingaging causes problems in my eyes.
