Make sure you go to get an alignment after. Go to a good place too. Not Tirekingom or a place like that because all they do is set the toe
It's hard to align the trucks with the c2c kit. I was able to get mine within specs when I was lowered with c2c, but that's because the tech had to bend out the tabs for the eccentric cams. If he does not do that, the truck will not get in alignment.
