Silverado going in for a makeover. what to do?

[cofi]

Actually going to a lower (numerically higher) gear, is going to help mileage, as your engine doesn't need to work as hard to get things going. I'd make gears/locker/armor top priority if it were me.

this is right and wrong

taller gears(numerically lower) will be better on the highway keeping your rpms low shorter gears would be better for city driving/ off roading

if it were my truck(im on 37"s with 3.73s myself) i would leave the 3.73s and if your serious about wheeling get an ORU doubler for the low and low low range stuff

get lockers in the rear(and a 14 bolt rear end if u dont have one)ditch the IFS bullshit in the front and throw a locker dana 60 on the front

bumpers....your better off having someone local build em tactical armor groups are great when there not drinking that day but i have seen some fucked up twisted bumpers come out of that place
