I have a 93' F150 with a 4.9L,E4OD and Borg Warner Tcase. I'm running 4:56 F/R with a Detroit in the rear and True Track up front. I want to upgrade for a little more torque. I'm looking at the Atlas Highlander and the Klune V. Any boby use one of these? Bronco graveyard says that the highlander is a bolt in job. Most of the venders say the Klune V is a bolt in too. I can see some drive shaft work and maybe some diff angle changes with it though.
