After going through two sets of Moog sway bar end links on my F-150,, with their Limited Lifetime Warranty, I decided to make a change. Local dealer didn't have any Motorcraft end links in stock but the local Napa had their brand in stock. Fine looking pieces, much more refined than the Moog pieces. The stock Ford parts went over 100k, the Moog links are only good for 10-15k. Guess time will tell.
