HPI Savage 21 Front and Rear Arm Lock Plates SAV1052 by GPM  [SAV1052]

This 3-piece alloy arm lock plate set is a replacement fit for the HPI Savage 21 chassis, supplied to secure front and rear suspension arm mounting points and cut down on pivot play that can upset suspension geometry.

Installation guidance: these plates swap in for worn plastic tabs at the arm pivot and use your existing fasteners. Make sure fasteners are torqued correctly, verify thread engagement and check arm travel and alignment after fitting to avoid binding or stripped threads.

Tuning note: adding alloy lock plates helps keep arm locations consistent under load, supporting repeatable suspension behaviour when you change spring or damper settings or push the truck hard off-road. Use them during routine maintenance or when fitting stiffer setups to limit unwanted movement at pivot points.
