I installed the 1LE sway bar and the next month i put a Powerdyne supercharger on. The new sway bar rubbed and it had to come off. I finally got around to fixing it. I put 2 steel pieces with holes drilled for the bolts and a notch for the bushing to sit in. I had to add 2 washers for the bracket since the energy suspension bushing are slightly taller. I cracked the old bracket tighting it down and needed to buy a new one. This is for anyone who buys this unit and has the SS sway bar. That SC is so damn tight in several places it is a amazing.

 

Or you could grind away a 1/4 inch of metal off the bracket that holds the head unit where it meets the sway bar.
That's what I did because my 1 1/4 inch aftermarket sway bar was rubbing and making creaking noises.
