Overview
This genuine HPI pack contains ten 3.8mm ball studs for the HPI VectR4 1/16 scale rally car. Ball studs form the pivot points that ball cups snap onto, letting linkages move freely while staying precisely located.
Worn or bent ball studs cause slop that makes a small rally car feel vague and inconsistent. Fitting fresh studs restores a tight, precise feel and keeps your setup repeatable.
