I wouldn't think .5" over the length of the jeep would even be noticable

 

There is nothing wrong with adding an additonal spacer up front within reason. Dont do it in the rear. I wouldnt stack two 2 inch spacers on top of each other but see nothing wrong with adding a .5 inch spacer to whatever u have. As a matter of fact, I did the same thing. I have a 3/4 inch spacer up front in adttion to my 2.5 coils and my bumper and winch saggged it so I threw in a .5 inch spacer on top of the .75 inch spacer to kind of level it out. Prob should ahve went with another .75 since I still have rake.
