Overview
The HPI Racing 6x19x21mm Cup Joint is a genuine factory replacement drivetrain cup joint for the HPI Savage X / XL. Cup joints accept the dogbone ends and transfer drive torque from the differential to the wheel hub.
Worn cup joints cause sloppy drivetrain feel and accelerated dogbone wear — fresh cup joints restore tight, confident drivetrain action.
