• Application: Stacks between the swing tower and the frame at the lower pivot pin, taking up vertical end play as the swing tower and bushings wear.
• Condition: Aftermarket replacement part

Common Use Case or Symptoms: Use when the swing tower has vertical slop or clunks when swinging, or during a swing tower pin and bushing rebuild — adding shims takes up the gap and stops the tower from rocking on its pins.
