HPI Savage 21 Graphite Front/Rear Arm Lock Plate by GPM GSAV1052  [GSAV1052]

Graphite arm lock plate set for Savage 21

This is a set of front and rear arm lock plates made for the HPI Savage 21 scale buggy, supplied by GPM as part number GSAV1052. The parts are RC-scale accessories designed to secure suspension arm pivots and reduce play at the arm mounting points while preserving the chassis’ intended geometry.

The plates are graphite, chosen for a balance of stiffness and low weight, and they mount at the arm pivot area to clamp the arm or its insert depending on Savage 21 configuration. In practical shop work this part helps maintain repeatable suspension alignment after impacts or rough runs, which makes setup changes more predictable.

Installation notes: the plates replace the original arm lock hardware location and use the vehicle’s existing mounting points. Check fastener torque after the first few runs and inspect for fit clearance around the arm and nearby components. No additional tools or parts are required beyond basic hand tools commonly used for Savage 21 maintenance.

Use these plates when you need a straightforward, durable method to stabilise arm pivots on Savage 21 cars during regular maintenance or when refining suspension setup for off-road conditions.
