I read some posts about people's difficulties installing lift kits with the rear not being jacked up high enough. I went to Sears yesterday and bought this GM SUV jack that will lift up to 21"
I also picked up these jack stands that will reach up to 21"
I have a smaller hydraulic jack that will reach 15" and jackstands that will go up to 17".
Will the 21" stands be tall enough to hold the truck up at the frame and give me enough room to drop the rear axle for the AAL install? If not, is it SAFE to place a block of wood under the jackstand? And one last question...since I have a second set of jackstands, what would be the best way to set them up as a failsafe? I plan to park the truck with the front tires against a curb as a chock.
