Whether using push-pull or crossover steering, it's important to keep the connecting draglink angle as close to horizontal as is reasonably possible (as shown here). As this angle grows steeper, so does bumpsteer. As the axle travels up and down, the angle and effective length from the steering box to the draglink connection point changes as the draglink angle changes. A steep draglink angle will cause greater steering change at the knuckles and cause the tires to twitch side-to-side as the vehicle encounters bumps and the axle moves up and down. Note that bends in a draglink do not in any way affect its geometry for this concern. However, bends are sometimes used to allow clearance between the draglink and some other nearby component.
