Hpi Racing 100862 Cup Joint 5X9X21.5mm

This is a genuine HPI Racing replacement cup joint, sized 5x9x21.5mm. Cup joints connect the transmission outputs to the drive shafts, and their engagement surfaces wear with every run, eventually creating drivetrain slop and clicking.

This factory-spec joint installs in place of the original and restores tight, positive drive through the driveline.
