My truck came with a dana 60hd (4.10 ratio) on it, this really didn’t compliment the dana 60 up front with 3.55 gears. Enter the dana 70u, this thing had wasted brakes and the powr-lok had self-destructed. But it was free.
1-ton (3″ wide) brake shoes and (1 ?”) slave cylinders.
ARB airlocker (thanks sutton engineering for setting up the r&p)
