Rough Country 1.75" Level Kit

I'm looking at ordering this leveling kit for my Tundra. I'm wondering if people are just putting this on without any additional modification aside from an alignment. Is anybody adding control arms, longer CVs, or anything else? How has ride quality been affected? The install looks very simple but any surprises on the installation I should know about?

 

I just did the levelling kit and alignment. With only 1.75" there isn't too much issue with the axle lengths or control arms. I am hoping to get a lift later but for now I like the level look of the truck. I put Timbren SES bump stops in the rear but those don't affect the level. My truck has the TRD Offroad suspension so red shocks and black springs. I don't have any air ride rear suspension going on.
