Need help on choosing gears? 4.10s,,,4.56s

I got an 04 silverado crew cab Z71. 6" lift with 35'' toyo MTs

i want to regear to get my power back also to get my fuel economy back around stock,
has anyone came across this?
I don't know much about gears..
If anyone can help me



Thanks, Abraham:chevy:

4.56. fuel economy?

4.56. and what about the power wise?
is there another gear ratio?

If you plan on keeping 35s and never going smaller I would go 4.56s. If you go taller then 4.88s. You will get back a ton of power by swapping up and should see a little bump in economy.

Thanks a lot Kerrige, I guess 4.56 it is.
I want to wake up my truck once again,

I am guessing you have 3.73 now? Also I would get a custom tune, Efans, p&p throttle body and a cheap CAI off eBay. Should get an extra 40hp and a little economy bump.

Yeah, I have 3.73s, I have magnaflow exhaust, and a CAI, vette servo, throttle body spacer, I also am Tuned By Nelskn Performance.
How much does that P&P throttle body run? I want e-fans. If you know any where I can get some pretty cheap.

Thanks for the link Chevy-Art.
Are gears hard to swap out? Has anyone done it them selves?
