I have a 7.5 inch fabtech and a 3 inch body lift. im adding a 1.5 inch coil spacer and 1.5 inch AAL. my question is will it cause wear and tear on my tires and will it cause my tires to tilt inward? also my truck should be leveled right? thanks for your help.

 

The coilspring spacers will throw off your alignment. If you don't get it aligned, yes your tires will wear out.
Also, the spacers and AAL should lift the front and rear about the same amount.

 

alright thank you for your help!
