For Sale: One pair of KYB SR4140 strut assemblies. I used these on a Grand Marquis for one month and 3600 miles. They perform better than OEM, but the car was a little higher in the front than I prefer. Most who have used these KYBs have cut a coil but I didn't want to go that route so I swapped them out with OEM Motorcraft replacement struts. These are like new. $150 for the pair.
