Quick question. 89 4.0 aw4 242 3" lift w/ 31's. I have factory 3.55's in it right now - I should have 4.10's. My question is this: What will 4.10's do to my a) gas mileage (I know, it's a brick, and the gas mileage doesn't bother me as it is now. To be honest, I'm not even sure what it's getting, but if it's going to be worse w/ 4.10's then we may have a problem. I do 90% on road/highway) b) top speed c) climbing hills at high speed.
I know that gearing will make a big difference off road, but anybody who has done the swap w/ a similar setup, I'd like to know what you have to say about the above topics.
Thanks. Here's a picture of an owl. wl:
