I use stock front end stuff and if I break anything it is the arms.
I had the GT2 arms on my truck for a while and never broke any front stuff. If I had to I would replace only the arms and leave the rest.
Just make sure you use the right hinge pins and kingpins otherwise you may find yourself breaking caster blocks because the pin is too short.
I accidentally used the kingpin for the outer hingpin and snapped the caster block on every bad hit. I changes to the right outer hinge pins and everything is golden now.

im hoping someone can help me. I remember reading on this forum a while back about an aftermarket diff rebuild kit for the b4/t4 that was made with much tighter tolerances and was supposed to last longer/perform better. I cant remember the manufacturer and really dont feel like re-reading everything to find it. Thanks in advance for any help.

A key to good diff life is to replace the spring every couple of times you freshen up the diff. The balls and rings can last a very long time but if the spring wears out and gets softer then the only thing you can do is bottom out he spring to keep it from slipping. The moment the spring bottoms out the diff feels much rougher. Fresh spring costs $2, very worth it. I've got 2 seasons of light racing (twice a month in winter on a very high bite track) on my balls and rings, they're still fine.

What is best weight front/rear %?

Never had a issue with the spring or the thrust bearing .
I only replace the diff balls & ring`s for a perfect diff that will last .
tip:
Make sure the slipper is adjusted correctly, if it is locked up your diff will fry early...

It can happen. I had a problem with my B4 diff not holding a setting. I had to tighten it too far to keep it from slipping. I removed the thrust spring and found it to be considerably more compressed than a new one. Put the new one in and all was good.
