The 2.2 LE wheels and SLW wheels have undergone some updates. The LE style of wheels are now called HD and are not compatible with LE rings. We are selling off the remaining stock of LE wheels and rings and will not be producing them anylonger. The HD wheels that replace the LE wheels now use 2mm hardware throughout and have some options when it comes to screw count on the beadlock rings. They are also lighter.
