Meet the Beast!! 10's on 5k???

thats alright you wanted 4:10s or 4:56 anyways didnt you??
btw,what rear do you have now,the 8-1/4?
those can be redone using a spacer instead of crush sleeves and hold up Very well too.
new gears are around 200 on ebay.
posi/limited slip chunks can be had out of dodge durangos dirt cheap.
almost all are 3:55....just use the chunk and install your gears and Axles from the truck rear.
check the glovebox for the codes.
