Axial 8.5x12 165lbs/in RC Slipper Spring - AX30413

The Axial AX30413 slipper spring is an 8.5x12mm replacement spring rated at 165 lbs/in, designed for use in Axial slipper clutch assemblies. Slipper springs are a key component of the slipper clutch system, controlling how much torque is transferred to the drivetrain before the clutch slips — directly affecting how your RC car handles sudden acceleration and rough terrain impacts. This black spring is sold in a pack of two, making it practical for a full replacement or to have a spare on hand.
