All JK axles feature stamped lower coil spring pads that are welded in place at the factory. As such, these brackets are set up exclusively for the factory-recommended pinion angle. This arrangement can cause problems when the pinion angle is altered. During extreme flex events, the driver-side rear coil spring can come into contact slightly with the rear track bar-making an annoying noise in the process. To combat this, Trail Master offers new heavy-duty, fabricated spring pads that allow you to clock the coil springs forward a few degrees to eliminate the problem. This photo shows the new spring pads in place awaiting welding. Before welding these mounts, Boddy lowered the vehicle so that the weight of the vehicle was present-in other words, these pads were welded last.
