Query: Good Upgrade/Replacement Choice

I installed these struts on a 2003 Ford Explorer XLT (front RSX17506 and rear RSX17507) as an upgrade and replacement for the worn out stock struts. Installation is fairly easy as long as you have air tools and the tool to compress the springs. The ride is noticably improved; however, I had been driving on worn the out struts for a little while. FYI these struts are the same as the Monroe Reflex struts and I have heard that these models may be discontinued (not confirmed though). Ordering through Amazon was great and by far the cheapest price I could find anywhere. I saved over $400 through Amazon and by doing the install myself.
