Ok i saw these and ordered up a set and was very happy with the results first off if you notice the way the front wheels sort of sag in at the top on the sp800 well once installed that is no longer there ....oh by the way you get a 5/8 inital lift just for putting these on then one click and your at another 1/2 inch up 2 clicks 1 inch ...witch makes the front higher than the back at that point ...and install was a breeze...45 min both sides ....Cheap and good ...
