lifting 2wd
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.
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.
