should i put gears in or not?

OK my truck is an 01 lifted 8inches and i have 37's on there i have some 4:56 gears for the rear but not yet installed, i bought these when i had 39.5s on there but have since went down to 37's. My truck currently has 3:73s, and i very rarley pull anything, it does have an edge programmer, should i install the 4:56s, sell em and get some 4:30s, or just keep em stock? opinions and why?

keep it stock if its a daily highway cruiser. if you drive in town all the time, 4.11s or 4.30s. 4.56's is too low for that size tire IMO.
I run 38's and 4.30s, alot of people run 37's and 4.30s, some run 4.11's with 37s, but they usually have 400hp+. changing the gears is not cheap either, so keep that in mind.

I vote for 4.30's because I think the truck drives MUCH better than with 3.73's but a lot of guys on here will tell you to stay put with the gears you have.

I have 35's and stock 3.73's and the truck drives and pulls awesome. The truck has no problem at all turning those tires, or burning them away. I do have some good power mods done to the truck, so that may have alot to do with it, but I dont ever seeing myself doing a gear set. I did a set of 4.10's in my old 86 chevy k-10 4x4, but thats because it was an offroad machine.
