I work for a suspension company and we had a set of these laying around so decided to replace my 90 Toyota's 150K + mile stockers. Beforehand I could push the rear of the truck down easily w/one hand and it would bounce 2 or 3 times. Now its much more stable but surprisingly it doesnt ride a whole lot better than it did with the puny stockers. Potholes and such are much better as well as rutted dirt roads but again its not night and day like i had expected. Next ill replace all the stock rubber with poly and see what happens but next time ill go with the platinum series. Thats my .02
