HPI Savage 21 Precision Arm Lock Plates SAV1052 by GPM  [SAV1052]

This 3-piece aluminium arm lock plate set is offered as a precision replacement for the HPI Savage 21 arm pivots, engineered to clamp front and rear arm mountings and reduce play that can compromise suspension geometry.

Installation notes for technicians: these alloy plates replace worn plastic locking tabs and are fastened with the chassis existing hardware. Verify correct torque values, ensure full thread engagement and check that arm travel and alignment are uncompromised after fitting to avoid mechanical wear or thread damage.

Performance intent: the rigid alloy plates deliver repeatable arm positioning under load to stabilise suspension and steering feedback during aggressive off-road operation or when using stiffer tuning setups. Fit them as a durability upgrade or as part of setup refinement to minimise pivot point movement.
