Rear risers to various heights, not 1.5". The driver's rear was about 1 inch and the rear left side was about 0.5 inch. Very upset. It may be acceptable if each blade adds the same amount of lift. I have ordered several shocks that require at least 1 inch of travel to install. Now it's a waste of time and money. Can't use them for long as I need another lift option to get my shocks working, but will update the review if the dive side sags and dips a little (don't expect the passenger side to go higher). I see other people saying they raised their back ends 2 inches or more. Sounds like a serious quality control issue.
