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

Durable cup joint for Savage X drivetrains

This HPI-86277 cup joint is an RC-scale replacement part made for HPI Savage X drivetrains, supplied as two pieces in a silver finish. The 8x14x19mm measurement is the key sizing detail to check before fitting, and this item is offered as a direct hop-up to replace worn or damaged cup joints in the Savage X driveline.

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

Tuning and maintenance role: this heavy duty cup joint helps preserve shaft alignment and reduce slop when in good condition. Check periodically for play or scoring, clear debris from mating faces, apply light lubrication where metal-to-metal contact occurs, and replace in pairs when excessive wear appears.
