The kit includes the caps and associated hardware that secure the trunnion shaft to the saddle, preventing walking beam separation and maintaining axle alignment. You replace these caps when servicing the trunnion bushings, if the originals are cracked, or if threads are damaged, ensuring the suspension operates safely under heavy loads.
