i just installed the srt shock and spring kit.the front was pretty easy,using the spring compressor was a little chore,not to bad though.when doing the rear end,if you chose the method of removing the lower control arm bolts,getting them lined back up is a little tedious.i did it by myself,it would have been a little easier to line up the holes with another person using the jack.also on the front when taking the springs of the struts there is a tool called the thru-ratchet.i bought it at lowes.it is made by kobalt.it allows access to the spring shaft so you can hold it while you unscrew the nut.
