I had these on my 08 titan pro4x made such a different in ride quality that I made it the first upgrade on my new 2019 titan pro4x they leveled the truck perfect 39.25 in front an back super easy to install just need a shop to compress the springs due to there a heavy spring. I tried to due it myself but the tool I rented to compress the springs went to hell on me an we couldn't get the spring compressed enough to install new strut. My suggestion to anyone doing it is just try an find a good local shop to compress the springs and swap the struts out for u. I did read in other comments that to reuse the dust boot u had to double stack the washers with the old an new I didn't have to do that. Literally just swap out everything that comes with strut ,washer, nut. Use the second to the last notch to level the truck. Would definitely buy again and would definitely recommend.
