lifting 2wd
 

I'm gonna lift my 2001 chevy blazer 2wd. And wanted to know will it look good with 2 in body plus 2 in rough country with 31s? Reason I wanna do both is I don't want my 31s to rub when I hit bumps in road or on my dirt road? Also, should I go with 3.73 gears sence I want my truck to feel like stock with 31s? Thanks

What gears do you have now? 31"s are just a couple inches taller than factory 235/75's, so I wouldn't think a re-gear would be needed. If you really want to see where you would be, there are gear ratio calculators online, and you can compare your current setup to a new one.

I have 3.42 now I just don't want it to be that sluggish sence I'm a vol firefighter

if you dont change the gears, you will be at about 3.20:1 on the rear end.
if you want to keep the same performance, you would basically need a 3.65:1 rear end.
so yes, you would want to change to the 3.73's if you want it to drive the same. if you dont change them, you would effectively have a 3.20 as your rear end gear. you might be sluggish off the line but then it would start to "freight train" when you get high in the RPM range. i dont know if you will be able to find a 3.73 rear end in 2wd. you might have to buy some parts. which wont be cheap. unless you know how to set up a rear end yourself.
just my .02

if you like seeing all that frame exposed then ya a body lift looks good, personally i could never bring myself to do it

oldsmobile bravadas has 3:73 with g80 on some of the 2wds. and direct swap out too with ours. (make sure its 2wd for 2wd,and 4wd for 4wd)

bravada's are all awd which is similar to a 4x4 except the front axle has no vacuum actuator
