3.73 gear swap
Just swapped the 2.73 for 3.73 in the factory posi. I know there is a lot of debate about the best ratio. All I know is this woke my car up! I love this ratio. Don't plan to use it on the highway, but man o man is it fun around town. Put new Lakewood lower control arms and took the fuel pump out of the tank while we were at it. 3.73 get's my vote. Now we'll see how long it will hold together!
