HPI Savage 21 Alloy Front/Rear Arm Lock Plate by GPM SAV1052  [SAV1052]

This is an RC-scale replacement arm lock plate set manufactured by GPM for the HPI Savage 21 chassis, supplied as 3pcs. The parts are described as alloy lock plates for front and rear suspension arms, intended to secure arm mounting points and reduce play that can affect suspension geometry.

Installation notes: these plates replace worn or damaged plastic lock tabs at the arm pivot area, and are fitted using the vehicle's existing mounting hardware. Check fastener torque and thread engagement during installation to avoid stripping, and confirm arm travel and suspension alignment after fitting.

Tuning role: alloy lock plates help maintain consistent arm positioning under load, which supports repeatable suspension and steering behaviour during setup changes or aggressive off-road use. Use them as part of routine maintenance or when moving to stiffer setups to reduce play at pivot points.
