Ive ran 5.71's theyre freakin sweet for 40's on a toy. I beat the 
out of my truck and the 5.71s held up for days until i bound my driveline climbing a wall and it caused me to lose about 4 teath on the ring gear. That wasnt bad it was the sheard off my output shaft in my tcase that killed me. So yea the 5.71s arent as weak as people think...
And we have proof now
5.71s chipped teeth while the t-case sheared an output shaft.
