Lincoln is known around the world for the ride, and they achieve said ride with Motorcraft shocks.
I replaced my front shocks about 6 months ago. It would have been $13 a shock for Gabriel's and $25 a piece for Monroe Sens-A-Tracs. I have used both on cars that I fixed to sell, and they are good aftermarket shocks, that most of the time are better than OEM;But Lincoln is in its own class as far as suspension, so I bit the bullet and paid $33 a shock for Motorcrafts.
I am assuming you are talking about the front shocks and not the rear air shocks/bags.
The ride is just amazing with Motorcraft shocks and the price really isn't bad for what you get.
Good Luck,
