got the springs installed took like 30 minutes easiest springs I have ever done, you do not need to remove the shock from the tower with stock springs, I now have 5 1/2" of travel, i also swapped out the shocks under warrenty since one was missing the lower bushing, i only drove a few miles and the ride is nice and firm now even over railroad tracks

unlike others said with their springs these were not marked left / right
