These three alloy lock plates are supplied as replacements for the HPI Savage 21 and are intended to clamp the front and rear arm pivot points, reducing play that can affect steering and suspension behaviour.
How to fit: they replace worn plastic tabs at the arm pivot and use the vehicle's original mounting hardware. Verify bolt torque and thread engagement during assembly and check for any interference with arm movement after installation.
Why fit them: alloy plates keep arm mounting points more stable under load, helping you achieve consistent suspension responses when tuning or running rough terrain. They are a straightforward upgrade for routine maintenance or firmer setups.
