i always thought all pro's were 4130 axles? i think alloy rear shafts are a waste of money, though...
I gots to agree with da kyle...unless you run 40's and POUND on your rig, I don't see you breakin a rear axle. Front will go first. Bu then again, its an s10? Spontaneous explosion?
Hey kyle, you been hiding out somewhere? I feel like you haven't posted in a while.
