This 8-piece pack includes steel king pin screws specified for the original HPI Savage 21, supplied as aftermarket replacement parts. The screws are used where king pins retain steering and suspension linkages and are suitable for routine maintenance or when making setup changes.
Guidance focuses on confirming fit and engagement rather than detailing measurements. Swap out worn screws one at a time to preserve component geometry, verify thread engagement and apply torque carefully to prevent stripping, and inspect the mating bushings and bearings before reassembly. As steel fasteners, choose and apply a thread locker appropriate for the type of off-road running you do.
