Living with 3.91's

I have 3.90's in a Dakota. It turns 3000 rpms at 60 mph and a 27.7" tire. If you don't do a lot of freeway driving, you should be fine.

Agree. I have 3:91 gears with 26" tires and its great around town. I can cruise at 70 MPH on the highway for long distances but it revs pretty high and its not something you really want to do very often. So if you aren't going to do a lot of highway driving they are great street/strip gears.
