Neuma 4 Spring

Extra springs! These are steel springs with a passivation process done to prevent corrosion.

Use Heavy Duty only if you are having trouble stabilizing Regular springs. Heavy Duty is primarily for use with cartridges with very light spring tension, and regular springs for everything else.

WARNING: Using Heavy Duty Springs with cartridges with strong spring tension can overload the motor and reduce its lifespan! Use only if necessary.
