Hey guys i can't decide on what gears to get...obviously between 3.73 and 4.10. I know this is covered A LOT but my dilema is for a different reason. To what extent do gears have on engine wear, especially between the 3.73 and 4.10. I do 2 days of highway driving a week which is only about a 25 mile drive one way so this might have a factor on the wear as well. Also I plan on getting cams in the summer so which set up will be better with the cams. I will be adding a chip/tuner pullies, and TB/plenum as well. Oh and I almost forgot. Since I have about 56000 miles on the car I will order new bearings with the gears, but what about that installation kit? Thanks in advance, Dan.
