^^^^^^lmao. I've used those hunk of crap compressors when I did a lift on my old FJ.
But looking at that shock in the background and the size of the spring...I don't think he needs a compressor. That looks like a pull the control arm down and use a floor jack.
We just had one sheer the nut off and shot out of the machine just missing my tech's arm as it launched out. Luckily he is very experienced so he knew to keep clear because it would have broken his arm without a doubt. We've had one launch out and hit 30ft ceiling before. Dont **** with springs unless you have the equipment.
