HPI Savage 21 Arm Lock Plate Upgrade Set Alloy-7075 SAV1052H by GPM  [SAV1052H]

Arm pivot lock summary

This Alloy-7075 lock plate set is made for the HPI Savage 21 to secure the front and rear suspension arm pivots. The metal plates replace the standard lock plate parts and are supplied for RC-scale use only.

The plates fit to the existing pivot locations using factory hardware points. When installing, confirm the pivot pin is aligned and use correct torque on the mounting screws to avoid thread damage. The kit includes plates for both front and rear positions as shown in the title.

Using metal lock plates reduces pivot flex compared with thin plastic options, which helps retain consistent suspension geometry under load and supports more predictable tuning of ride height, camber links, and shock mounts on Savage 21 setups.

Use standard RC hand tools for fitting and ensure adequate clearance to steering and suspension parts before driving; check hardware tightness periodically.
