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

Precision-fit cup joint for Savage X

This HPI-86277 cup joint set is an aftermarket replacement for HPI Savage X drive systems, delivered as two silver-finished pieces. Verify the 8x14x19mm dimension to confirm fitment; the part is intended as a direct hop-up to renew worn cup joints.

Fitment tips: remove the driveshaft assembly and change one joint at a time, check the orientation when seating the new cup into the yoke, inspect drivepins and surrounding driveline parts for wear, and reuse factory fasteners following the original torque guidance. Standard RC tools are all that are needed.

Tuning impact: installing fresh, tightly fitting cup joints reduces slack in the driveline and can improve throttle response and predictability during aggressive runs; maintain cleanliness and apply minimal lubrication to sliding surfaces as needed.
