I installed these shock absorbers to replace the old ones. They seem to have changed the handling of my truck. The ride is pretty good, not as smooth as before. They're a bit stiffer and don't handle turns well, but when the truck is loaded or towing a trailer, it doesn't squat as much either. So I gave up the smooth ride and unencumbered handling in favor of better towing and towing. As I don't tow or tow as much as I used to I would rather leave things as they were but the old ones had over 180k miles on them. They also belonged to Monroe.
