[QUOTE="Galen Burden, post: 955557, member: 66840"] I dont think you will notice much difference between the 3.55 and the 3.73 gears. I had 4.30's put in my 2wd 4.6 Limited and I absolutely love it. I tow a small boat in the summer and the difference is pretty dramatic. Fuel economy remained unchanged with the 4.30. The 6 speed trans has a double overdrive and at 70 mph mine was turning 1800-1900 or so rpms. The 4.6 makes zero torque there and the slightest hill made it downshift twice to maintain speed even when not towing. With the 4.30 at 70 mph, it turns 2400 rpm which is a much sweeter spot for the motor. When not towing, it rarely downshifts unless you snap the throttle pretty good. If I was doing it again, I would probably go for 4.56 but I would recomend it without actually trying it my self. I got the idea from this post on another board. I am very happy with the results. http://www.explorerforum.com/forums/showthread.php?t=220833 [/QUOTE]
