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

Arm lock plate upgrade for Savage 21

This item is a front and rear arm lock plate set made for HPI Savage 21 and identified as GSAV1052. The components are graphite clamp plates aimed at securing suspension arm pivots and reducing unwanted movement while preserving the designed chassis geometry.

Graphite is selected for its combination of stiffness and low mass, and the plates fit at the arm pivot area to clamp either the arm body or the insert depending on the Savage 21 arrangement. In practical use the parts help keep alignment consistent after rough landings or hard driving, simplifying suspension adjustments.

Installation instructions: the plates replace the stock arm lock location and use the existing mounting points on the vehicle. Check fastener torque after the first outings and confirm there is adequate clearance around adjacent components. No specialised tools are needed beyond standard Savage 21 hand tools.

Fit these plates to gain a practical and robust method for stabilising arm pivots on Savage 21 machines during routine maintenance or suspension tuning.
