I got some bad news a couple days ago when I took my car into the shop. My rear end needs a rebuild. Now is the time to change gears. I like everthing I have heard about the 4.10 but I drive on the highway a lot and cruise anywhere from 80 to 90mph. Is the 4.10 gear gonna be ok for that kind of driving? I wanna hear from people with 4.10 gears and how they are on the highway at those speeds. I dont care about mpg.

I've commented in depth going on and on about why to go 4:10 haha. But just do it! No regrets regardless of highway and if you do 3:73 you will leave the shop wishing you went more.. That's for sure! If you have 3:55 already you won't even notice the difference. Go 4:10 and don't even question anything else. And yes you will have to change the speedo with a hand held tuner but don't need a tune.
