I want to put a 6" lift on my 2001 4dr 4x4. Any sugestions? Will it fit 32's also?

Yes, welcome!

Please note that the above link shows a ZR2 Blazer which is already lifted when compared with a regular Blazer.

And yes, with a 6" suspension lift, you should have no problems fitting 32" tires, but you may have to put spacers in to push the tires further outboard to better clear the frame with the steering at full lock.
