That's correct, EXSlider400. I just bought that part number and the four factory bolts needed to install it to the frame. (11518341) and installed on my 2014 LT, 4x4 without z71. As far as I can tell, that's the only skid plate that the z71 has over the normal 4x4. It took some manual cranking with a 15mm socket as the frame holes are threaded but sprayed over. Had it all done within 10 minutes.
