Supreme Suspensions Wheel Spacers

So, these are lightweight but sturdy. My only complaint is no directions. Not that it is brain surgery but still. So, the nuts on the lugs that are on the spacers need to come off and be used on the submerged lugs (in other words, use the packaged nuts to secure spacers to truck, use lugs from truck to secure tire to spacers). I have a slight vibration over 85MPH. This may be because I think my one tire I did not take off one of those stupid star retainers (you know, the ones that are from factory that help hold the disks to the lugs?). And that may be causing the vibration. However, I have not had time to get in there and redo it. I just towed 6k 1000 miles with no issues from the spacers. In short, they are great and fit perfectly with my factory tires and rims (2016 Ram 1500 Eco).
