I have the yellow aluminum jack from Sears as well that I use on my Springer. Have never noticed it lifting up on the shocks- maybe I need to pay more attention, but I think I position it far enough forwad it only hits the frame. Anyway, I position it from the left side of the bike- have never tried the right side- might be better. Everytime I lift it just so the tires are off the ground, then give it a little shake to make sure it's stable. Haven't had any trouble so far. It seems like it would take a lot of shaking to knock it off balance. Thats how I do it anyway.
