Has any one used these from Harbor freight? I think they might work since they have arms that reach out and grab the springs instead of having a bolt right at the springs. Im going to be pulling and installing my springs a good bit to find the right ride height and Im using a floor jack to remove the springs and it is so timing consuming. http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=43753
Those are going to require the strut/spring to be out of the truck otherwise you may never get it high enough especially if youre looking at the 300Z's srpings
harbor freight has some that are 2 giant screws with hooks at the top and bottom, you still have to remove the shock, but those are the ones I use all the time, they are great. sometimes on wacky springs you might have to put a vice grip next to one of the hooks to keep it from slipping, but other then that they are perfect. http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=3980 these ones. and they are cheap!
Ah, just cut a spare spring to see if I would need compressors to get them in and I dont, just a little help with the jack and they go in fine... getting the stock ones out are a pain but ill just have to jack the control arm with a jack.
