I have a 01 TJ Sahara edition, with a 3 inch teraflx short arm lift on it running 32x11.5 Goodyear MTR's .. I do a fare amount of off roading with it but also a lot of highway driving with the 70MPH speed limits... if there is any head wind at all I cant get it to break 75 unless i shift the auto transmission into second gear. at 70MPH im only running about 2100-2200 rpms.. I cant say for sure but im guessing im running 3.73's I instaled a K&N cold air intake, helps with get up a bit but cant tell much difference with the top end. I got an extra 200lbs or so with a warn front bumper and 9000lb warn wench which I doubt makes much difference. I have a 30 in the front and a 35 in the back and am looking at regearing, with my next tire change Ill pry just throw on 33's.
Will I notice much difference with 4.10's or should I go for 4.56's ? or will that be running my RPM's to high around 80 mph?
