Tech Insight

The cap ring plays a critical role in:

  • Securing the shock cap assembly under nitrogen pressure
  • Preventing cap movement during high speed compression cycles
  • Maintaining structural integrity of the shock body

Improperly secured cap rings can lead to cap loosening, nitrogen loss, and inconsistent damping performance. Always torque and secure the set screw according to Radflo service procedures during rebuild.

For race or heavy-use applications, inspect cap rings during every shock service interval.
