Well, I just finished installing my rear links and rear shocks (Bilstein HD). I used a floor jack under the lower control arm to move it up and down to align the holes of the links and the shocks. No problems with the shocks. No major problems with the links. However, the new bolts in the kit have a "torx head" (T-55, I think) and the clearance between the brake rotor, frame and other links is very, very tight. I suggest, make sure you have all the tools necessary for the job BEFORE you handle this job.
