I don't know if it is contributing or would fix your problem but there is no way on Gods green earth that I wouldn't be running double adjustable shocks all the way around and at a minimum at least on the back......if the tire sticks then spins or unloads and rehooks again my first thought......obviously haven't seen a video.....but by your description is that the compression is too soft in the rear and is letting the tire rebound after the hit.
