HPI Savage X Heavy Duty Cup Joint 8x14x19mm by JAZRIDER HPI-86277  [HPI-86277]

Heavy Duty cup joint for Savage X

This JAZRIDER HPI-86277 cup joint is an RC-scale replacement part tailored for HPI Savage X drivetrains, supplied as two pcs in a silver finish. The 8x14x19mm geometry is the key sizing detail to confirm during fitment, and the component is offered as a direct hop-up part to replace worn or damaged cup joints in the Savage X driveline.

Installation notes: replace one side at a time and inspect surrounding driveshaft components and drivepins for wear, remove the driveshaft assembly, slide out the old joint, seat the new cup joint into the yoke with correct orientation, then reassemble using the original fasteners and factory guidance for tightening. No special tools beyond common RC hand tools are required, but verify fit before final tightening.

Tuning and maintenance role: this heavy duty cup joint serves as a drivetrain wear item that helps maintain shaft alignment and reduces play when in good condition, it should be checked periodically for slop or scoring, cleaned of debris and lightly lubricated where metal-to-metal contact occurs, and replaced in pairs when signs of wear appear.
