I had absolutely no problem with shock length when I ordered my set of Road Kings in August 2011. I just told them that we had a 2006 Alpine and the Road King representative said what I needed was 2 #5A’s with ¾” x 1 ¾” spacers, and 2 #4-A’s also with ¾” x 1 ¾” spacers. I don’t remember which set went to the front or the rear, but when you look at them it’s self-evident. The price was $700.00 plus our CA tax for each set. It’s nice to know that apparently there hasn’t been the ever-present inflation to the price of Road King shocks. You are going to love the Road Kings, they really do the job. I went through the exercise of OEM Bilsteins and then Konis before installing the Road Kings. Yes, they are pricey, but well worth the money both in road handling and ride improvement – there definitely is a noticeable difference.
