I just installed a rough country 2" kit in my 2014 this morning. Both sides, the holes in the spacer were not drilled wide enough apart to match the spacing of the lower control arm. They were close, about 1\4 hole off, so was able make work, but what a pain. I called RC to make sure I ordered right part number, they said 1308 was correct for my truck. Has anyone else had this problem? I install RC level kit on my 2011 sierra and a Tahoe and had zero problems.
