Review on Powerbuilt 5-Piece Coil Spring Compressor Tool Kit - Remove Straight/Curved Coil Springs, Shock Absorbers - Foreign & Domestic - Includes Storage Case (648603) by Michael Santos

I used it to install front coil springs on your typical GM RWD 2WD car. I quickly found that the threads would be too long and would stick out too far from the top and hit the frame. So I cut 4-1/2 inches off the stem and it was good. The arms of this compressor are also not offset enough to parallel guide the tool in the spring, it works but it makes it unwieldy. I had to compress my spring from 14 inches to about 10 inches to mount it with the lower control arm hanging from the spindle. Make sure you are seated in the top of the frame bag and that the spring is properly seated in the lower arm. It is also difficult and troublesome. Don't plan on installing springs in a well painted frame this way without damaging the paint, it's impossible! I used rubber isolators and if I have to do it again I could pre-glue them to the spring with o-ring glue. You don't stay down! I prefer this job on a vehicle, I'm not trying to restore nicely where you have the weight of the engine and a jack to put those springs in. Long post I know, but these are my observations and I hope to save you from some of those disappointments!
