Yes, the spacers are for camber..SkyJacker also sells Camber Bushings to go with the kit..As far as installing it yourself...Yes, not to many tools needed..If I remember right....15mm for eyebolt..18mm for U-bolts..15mm for Shock mounts...1 1/8 socket for Coil spring mount. Think the sway bars are also 15mm.and a 13mm for the top shock mount..So a basic metric DEEPWELL socket set, and basic Metric wrenches.
I ran the SkyJacker lift for about 6 months..Loved it..Sold it to another member 6 months ago, and as far as I know, he is happy with it.
I did the install in a days time.
Good Luck..
BTW...Try the search feature, if I remember right, several of us posted install instructions when Boats was doing his.
