The Atlas Spring crew fitted a torque wrap to our pack. The torque wrap runs only from the center of the spring forward to the spring eye, and it sits on top of the main leaf and wraps down under the spring eye. As the axle tries to wrap up, the torque leaf tries to pull it back down and cancel out wrap, which can bind driveshafts and cause general mayhem. We have found that in anything less than a healthy V-8 these work great. Otherwise we would consider also adding an anti-wrap bar.
