HPI Savage 21 Front/Rear Arm Lock Plate Upgrade Alloy-7075 SAV1052H by GPM  [SAV1052H]

Arm pivot lock details

This Alloy-7075 lock plate set is manufactured for HPI Savage 21 to clamp the front and rear suspension arm pivots. It is intended as a direct replacement for the stock lock plate parts and for hobby RC use only.

The component installs at the existing arm pivot points using the stock hardware holes. During fitting, check pivot pin alignment and properly torque the mounting screws to protect threads. The product is supplied as a set that covers both front and rear positions as referenced in the title.

In tuning terms, replacing thin plastic plates with a metal lock plate reduces flex at the arm pivot and helps keep suspension geometry consistent under load, aiding adjustments to ride height, camber links, and shock positions on Savage 21 builds.

Fit with basic RC hand tools and confirm there is sufficient clearance to steering and suspension parts before full operation; recheck hardware tightness after initial runs.
