PolarStar Kythera SA Small Spring Set (Excluding Valve Spring)

Keep your HPA system running at peak performance with the PolarStar Kythera SA Small Spring Set, a must-have maintenance and replacement kit for Kythera users. Designed specifically for the PolarStar Kythera SA engine, this spring set includes all essential internal springs—excluding the spool valve spring—to restore crisp trigger function and reliable cycling.

Whether you’re performing routine maintenance or refreshing a well-used build, this kit ensures your Kythera continues to deliver the mechanical precision and consistency it’s known for.

Essential Maintenance for Your Kythera System

The Kythera SA is a fully mechanical HPA engine, meaning its performance relies heavily on the condition of its internal components—especially the springs.

Over time, springs can:

• Lose tension
• Wear from repeated use
• Affect trigger feel and reset
• Impact overall cycling reliability

This small spring set provides a direct replacement solution, helping you maintain factory-level performance without needing to source individual parts.

Complete Internal Spring Coverage (Excluding Valve Spring)

This kit includes all the critical springs used in the Kythera SA system, ensuring your trigger mechanism and cycling components operate smoothly.

Included components:

• Trigger Spring with Pad – Maintains consistent trigger return and feel
• Disconnector Spring – Ensures proper reset and engagement
• Recocking Latch Spring – Supports reliable mechanical cycling

By replacing these components together, you restore the balanced internal operation of your Kythera engine.

Restore Crisp Mechanical Trigger Feel

One of the standout features of the Kythera system is its realistic mechanical trigger response. Worn or weakened springs can negatively impact this experience.

With this spring set, you can:

• Bring back a crisp, clean trigger break
• Improve trigger reset consistency
• Maintain realistic mechanical feedback
• Ensure reliable semi-auto operation

For players who value precision and realism, keeping these components in top condition is essential.
