gear changes on 01 blazer
 

I wanna get a body lift for my 2 door blazer so I can fit 31s? How much would it cost to change gears to 4.11?

Gears plus install kit depending on where you buy them
From range in price greatly. Plus the install labor cost. I usually figure total cost per axle on the low side about $1000 each axle. Its the
Labor that seems to really gets you

2wd drive? like okiedoak said, about $1000 each.
but you dont HAVE to have 4.11's for 31's. what do you have in it now? 3.73's? 3.42's?

double post....

31" tires will run just fine with 3.73 gears, and are very common in blazer axles which can be foundbin almost any salvage yard a lot cheaper than a full gear swap. Plus you dont need to be a rocket scientist to do the install
