[QUOTE="voodoo96743, post: 571087, member: 5752"] IDK what the mpg drop would be, but it is caused by an increase in rpms. With 3.55:1's in 5th gear at 75mph you would be at about 2,100 rpm. By increasing the rear end gear ratio, it moves up the rpms at all speeds, so you would be running at higher rpms, thus less fuel efficiency. Thus 4.10's in 5th at 75 would equate to about 2,400 rpms. 4.30's would be about 2,550 rpms. [/QUOTE]
