Your tach will read 14.1% higher with 3.73s and 25.4% higher with 4.10s. I like my 3.73s. I'm still running below 3,000 rpms at 80 mph on the interstate. There is a con to any gear change. I lost 2 mpg when I changed to 3.73s.

Have you thought about going to a taller tire to water down the gear? If I calculated it correctly 255/50-17s or 245/45-18s would make the 3.73s behave as if they were 3.55s.

I love my 3.73's and when I go with a supercharger it should be just right.

I wont give up the appearance of my tires for another size. We'll see how everything goes after I pull the car back out.
