a 60 would be overkill but if you ever plan to go to 40's or so the initial cost is well worth it to not have to change axles later on. i see so many guys go from d30s to d40s then to d60 and then end up with rockwells. so overkill is never a bad thing.
Yea d40 or d44 would be the way to go for sure i think there are some issues with using the ford 9" i vaguely remember something i was told at some point...
Thats funny the little pickups should know better....are you open or locked?
Yes it works very good theres a few vehicles that we dont have the computers mapped yet (volvo,some chrylser,09 duramax,09 cummins) other than that works great
