Normal
The + implies 3.0's (or Kings) on the front - which no longer have 3 perch settings to choose from (see Bo's post above). Instead, the 3.0's are threaded for a full range of adjustability - including an equivalent to the top perch setting. After they are installed the front 3.0's need time to "settle" which mine have done. I now plan to run them up just short of top perch - where I stop is to be determined by the maximum height that will still minimize stress on the cv joints
