which gears to upgrade to
right now im running 3.08 gears and i was wondering what the difference would be if i went with 3.73 or 4.11 gears and which gears to run. i do mostly city driving and i dont worry too much about mpg but also about how much would they drop with the upgrade?

ok so between the 3.55 and 3.73 whats any big difference. ive tried to learn about gears and such but i just end up getting confused. lets just go with the 3.73. would i feel much of a difference in acceleration from my 3.08? if i understand this 3.73 would give me better accel because rpm's would be higher but it would also cut my top speed.

something no one mentioned is that the "3.73" refers to what is called an underdrive ratio ( a 0.90:1 or less is considered overdrive). in other words, your drive shaft turns 3.73 times for every one revolution of the wheel. to lower the mpg, you would want to probably drop the ratio to less then what you have now, something like 2.90:1 or smaller.
have you factored in the cost as well?? parts and labour??
really the only time you should be changing out the gears, is when you change other factors like tire size and trans ratios which effect your final compound ratios of your driveline/powertrain. if your truck came with 225 and 3.08:1 gears then im sure someone got paid allot of money and spent allot of time in research and development to determine an ideal size that would give the specific vehicle the right balance of torque and acceleration.
just my 2 cents.

For you I'd go with 3.73's if you do mostly city driving. 3.55's would be better on the highway because it keeps the RPMS down. The easy way to understand gears is that the higher the number goes the easy the vehicle can spin the tires. With that same idea the higher the number goes the higher your RPMS go. Are you positive you have 3.08 gears?
