Just used these to do the front struts for a 2012 Mustang. Compared to the simple hook-type I've used before, these take a bit more time to set up... but once installed, they are a lot more secure. They rely on the screw only for compression while any bending stresses are taken up by the large outer tubes, so they stay straight and are probably less likely to fail. They don't try to 'walk around' the spring.Very glad I got them.
