Thread: 3.73 to 4.11s - Is it worth it?

Tweet

I have a Supercharged Suburban with 3.73s in the rear. I just put 20" wheels which added about one inch to my overall tire diameter. This slightly affected performance, so I'm considering going to 4.11s. I'd go a little higher (numerically ), but the next step is 4.56s. I think 4.56s for a daily driver would be a little to steep. Is a change to 4.11s from 3.73s going to be noticeable? I don't want to spend the money and have little to no difference in performance. I think I can live with the slightly higher RPMs on the freeway.

you should gain about 500 rpms to go the same speed that the 3.73 was running across the board.

I upgraded to 4.11s and the difference in performance is noticeable. If I could do it again, I'd go with the 4.56s though.
