Mojave Mojave best drivetrain upgrades

[Sundayracing]

So I've been out of workin on my Mojave and stuff for hunting seasoning lol and now that that's over I'm getting back in and man what a bounty of new exb parts to wonder about.. So I have some questions about bulletproof drivetrain. I don't really bash my Mojave but I have a race track I use it on, and I have never had a diff problem unlike my outcast I broke them every battery pack..I have noticed all of my dogbones pins are filed down and all of my diff input and output cups are completely shot, the slots are egged out to where they almost let it the dogbones free spin. So where should I go for upgrades?
I could just replace stock parts as they lasted me all last year and really still haven't failed completely yet just real sloppy.

Only aftermarket dogbones I found are gpm? Better then stock?

Could buy the new complete lsd diffs from exb? How are the new exb center input cups holding up?

Or rebuild my diffs with m2c cups which are pricey?
