Ok here is the question. Can you break anything from a roll? Im sure you can but is it the type of thing like stock irs from a dig? If its deffinate, what will break? Would like to know if my rearend will hold up if i have: 4.10's, 2.76 upper, possibly 4lb lower, cold air, catback, midpipe, Pro.50 and bfg drag radials. All on stock untouched irs. Im not planning on runnin at the track(from a dig) until i atleast get some QA1'S. With all this said, will i break anything? thanks you all.
