Axial AXIC0413 Slipper Spring 165lbs Black

This Axial Slipper Spring set includes two 8.5x12mm springs rated 165lbs/in in black, used to set the pre-load tension on a slipper clutch assembly across several Axial platforms. Spring tension determines how much torque the slipper allows before slipping, an important tuning point for drivetrain protection.

Because it's a genuine Axial part built to the standard 8.5x12mm slipper spring specification, it's a direct-fit replacement for a compatible slipper clutch assembly, without requiring any modification.

This is a functional tuning and replacement part rather than a cosmetic upgrade, intended for owners doing slipper clutch maintenance or adjusting slip tension. The set includes two springs per package.
