S197 Mustang Spring, Strut and Shock Install We recently added a couple new suspension kits by Ford Racing and Jarrod could not wait to get one of them on his 2013 Mustang GT. Jarrod went with the non adjustable Ford Racing 2005-13 Mustang Strut, Shock And Spring Kit. Follow along with the installation here! This is about as detailed as we can be with a suspension install. Most people might already have a good idea of how to install these parts, but for the people that have yet to do anything, there is a ton of information here.
