I wanna install a 2.5 - 3 level kit on my 2013 f150. My question is how hard is it on the upper control arms? I can get a tuff country kit 3 inch kit which come with the arms, spacers, and rear blocks with shocks but its a lot cheaper just to get the level kit spacer. I just plan on running 33x12.5 tires so i really dont need the extra lift just hate the dreaded front end sag!! How long would the control arm last under normal driving conditions is what im getting at?

 

I'd go with a 2" as you'll be able to fit 33s with it. A 3" level is going to give you pretty severe angles and probably ruin your front end. Also, it's not the upper control arms you should worry about, it's the ball joints in them, the lowers too, tie rods, cv joints (if 4x4).

I had my truck lifted two inches up front and just went back to stock. It's rides so much better now.

Bottom line, if you really wanna level it, get a 2" spacer for about $30 and save your money.
