Ford's price is for two shackles, not one. So the price is $215 for a pair. Read the details in the description and it clearly indicates plural nouns so there has to be more than one in the package. Also, look at the shipping weight. 6.55 lbs for one shackle, I don't think so.
Updates per Ford
Grease fitting added to lower shackle tube
bushing grease groove improvements
DOM center tube tolerance improvements
Also interested if it will work with powerboost. Only concern is the routing of the power line to the rear.
