I have used Love's Truck Center for replacing the Struts on my Sprinter 3500 with Koni Struts. As I recall the work was completed within two (2) hours for about $200. They did an excellent job. I failed to mention I purchased the Struts from Agile, who specialized in Sprinter suspension for approximately $400 for the pair. I made an appointment at Love's and waited about one week.
