What are you guys running and what do you like about the new gearing?
Acceleration? Mpg?

Went 4.56 and very happy. Running a 34" tire and all the added weight and does very well, feels like stock.
If you go 35" or bigger I would probably go 4.88.
just an opinion.

Your best bet is as said to search for re-gearing info. There's tons of info/discussions out there that couldn't possibly be re created here.
Bottom line though, considering the cost of a re-gear there's really no immediate cost savings on fuel and once there is it's negligible. I can only speak for 4:56 gears but performance wise all the gains are at lower speeds and off road. Results will vary significantly based on your setup,tire size and type,vehicle weight, other performance mods etc.
All that being said still happy with my 4:56 gears after three years.

I went with 4.88's when I installed the 35" tires. That was before my supercharger. I think if I had the blower before I did the gears, I might have gone with 4.56's just to drop the RPM at freeway speeds.
Without a blower, if you are going with tires bigger than 33's, I wouldn't hesitate on 4.88's, they really helped with acceleration, climbing etc. considering the taller tires and all the added weight (armor, winch, etc.). If a supercharger is in your future, then you might want to consider 4.56's instead as you won't need as much help for climbing, etc.

Trust me MPG doesn't get better with a S/C. gets worse since your foot seems to gain 10lbs.

And there is additional parasitic drag.

Man I just need the supercharger because Im planning on pulling a 24ft trailer.
Right now I'm at 13mpg.

What are your RPMs at 75 mph with 4.88s? I might order 4.56 gears depending on how the SC changes things.

I'm running 35's ... So I'm at roughly 2500rpm

No, but it puts better MPG just a bit more out of reach. I think the blowers are a great option, but not for MPG.

That's cuz you a V8 brudda ...
I want the supercharger because I want passing / pulling power when pulling a trailer. And Im still dealing with the downshift to 4th gear when theres a big hill / incline. And any head wind forget about it...
I just was power to stay in OD ..

Maybe if I got 4.56 gears mpg would stay the same as stock, I just don't see how regearing could give better mileage than stock gears with the RPM being so low. Basically I'm just saying don't regear to help mileage because if anything it will probably decrease it.
Now with my 37's the 4.88s probably make more sense than with my 35's. More of an even tradeoff of power vs freeway RPM. But I have the V8 so make of that what you will.
