New to the Yukon platform and I noticed there are 2 distinctly different styles of leveling kits. One is basically a U shaped bracket that mounts at the bottom of the strut. The other appears to be a round spacer that melts at the top of the coil Spring. That seems more secure and safer but what is everyone's thoughts on the much cheaper U-shaped bracket at the bottom of the strut? Looking at the Rough Country one but open to other options.
