I'm done with exhaust issue. Now i need help in selecting gears. I do a lot of driving in city and highway. For guys that don't know i have a 08 4.7 ram. I would like a performance part that if i'm rolling on the highway and one of those chum buckets trys to get stupid, i can get up and go hard. I don't want the truck to get lazy and i have to wait for it to kick in and take off. Or in a complete stop for it just to take off with out the truck getting lazy. Any advice is very welcome so far all advices given here are correct. Thanku guys.

 

what gears do you have now? I'd recommend gears. if you're stock height and dont plan on lifting it, most people say 4.10 gears are good. If you plan on lifting, it go 4.56. Some stock height guys that go 4.10 wish they'd just done 4.56 from the get-go so you may consider doing that.

Your city mileage will improve by 2-3mpg sometimes, and your highway probably wont be affected unless you drive over 75 mph regularly, then you can expect a 1 mpg drop

 

I do highway a lot and have 456s. I spin around 2000-2100 at 70 mph.

 

I have stock gears right now and i will lower the back 2 inch. And sometimes i do over 75.

 

Im trying to get a hold of nick from air ram for price on 4.56 gears but no luck.

 

I have stock 20s with 275/60 rubbers if that helps any. Im staying with stock 20s

 

You know, you can just edit and add to your post if you are going to post every few minutes....LOL

Stock 20s is safe to assume you have 3.92s but that is still assuming. Stock tires are 32-33"

Keep trying to call Nick, he will answer sooner or later.

 

That's why i joined the infantry cause i don't know anything else. lol.

 

4.10's or 4.56's if you have 3.55
4.56's period if you have 3.92

 

Now is it worth me buy from Nick the sonnax electric line booster if im buying the 4.56 gears ?
so it wont affect anything then just more improvement then. Also would i need sc flashpac imediately
after gear installation. Or i should be fine for a 1month with out tuner.
