Sway bars don't affect the roll couple a suspension sees. The roll couple is only affected by the lateral acceleration(turning force) and the distance from the centroid of the body(center of gravity at that point) to the instantaneous center(line drawn from each suspension member until it intersects, this intersection = IC).
By lowering and raising the end of the LCA, you affect how far the IC is away from the CG.
Sway bars are much simplier, they act like torsion bars(think of a spring that uses the motion of one suspension arm to affect the other suspension arm).
