Newbie question regarding lifts

What's up all?
Figured I'd ask this one, as I haven't seen it in the threads... I have a 3" Tuff Country EZ Ride on the way, and was wondering if there are any other components or considerations I should think about before heading to the garage with it?

Thanks, look forward to using the site.

 

How much does it lift the rear?

Measure your driveline flange distances (top and bottom) before you start the lift, so you can figure out what size shim to insert if you have driveline vibrations.
