i have a 1999 ram 1500 5.9 4x4 4 door short bed auto trans. in the back axle it has clutch packs on both sides of the spider gear would this be posi or limited slip or a locker? i know they are all similar. and what gear ratio would it be? the reason im asking is the back needs replaced and i have 35 inch tires and would like to know should i keep stock or go to a lower ratio i dont do much highway and my mpg sucks already someone said i should get either 4.10 or 4.56 i think
. wanted to know what you guys thought thanks.
