i race cars at the speedway and i have broke a total of 5 of those c clip elim... so i would not reccomend spinning doughnuts or circle track racing for that matter lol
how fast are you spinning those tires and racing puts a whole different stress on them then crawling.
Pretty sure he isnt going to be doing 6000rpm clutch dumps, or 100mph+ thru a trail.
So that being said, I find no reason a D44 and 12B will fail this guy anymore then any other axle will.
If he had a RamJet 502 V8 or something comparable, I would totally side with you and tell him he will brake 'em.
But I highly doubt he needs 1tons, or he would of stated so.
Sounds to me like he is souly going for the width and stability.
Now I think Lil Yota should post what his vehicle is, make, model, engine, trans, tire size, tcases? and purpose.
That would really help us out.
But like stated, C-Clip Elim, Ujoint upgrade, GM 1 ton Master Cyl, and brake lines made.
you could get away with the 12B drum brakes for now if you're on a budget.
Shed some light on us though Lil Yota
