I put the 1/2" spacers on my 2014 ram 2500 Laramie with the stock 18"wheels. I needed the extended lug nuts as well to get more threads on the stock lug studs. They recessed into the stock wheels perfectly even though the measurements on the website were not an accurate description in the pics. The stock lug nuts would only grab about 5 threads, not enough. This is the only company that offers a hub centric spacer less than 1" for the Ram. My only concern is the refund and return policy is not very customer friendly, which was the only bad reviews I could find about this company. Make sure you check and double check your own measurements and order the right parts and you will be happy. Hopefully the price will come down a little in the future.
