Im going to be 80 percent of the time dragracing and going to be dumping the clutch at high rpm with mickey et streets. Which differental should i buy? I want something thats going to take that abuse. I called detroit they said the tru track should be ok they have 9 second cars running them but i was leaning towards the detroit locker?

id get an electronic locker (or any good quality locker) with 31 spline axles and at least 4.10's if you are going to race it 80% of the time. brace your torque boxes, weld the axle tubes to the 3rd member, dif cover with the built in girdle and maybe brace the where the pinion gear goes into the 3rd member.
