HPI Savage 21/25/X Upper Shock Tower HSA-007 by 3Racing  [HSA-007]

Overview of the upper shock tower

This shock tower is intended as a single-piece replacement for HPI Savage 21, Savage 25 and Savage X models. It returns the upper shock mounting points to spec and supports suspension geometry adjustments on the listed chassis.

Fitting is aimed at hobbyists familiar with basic disassembly: remove the body and upper links where necessary, unbolt the old tower, transfer any reusable hardware and secure the replacement. The tower is a structural component and impacts shock angle and upper mount alignment rather than electrical or driveline systems.

After installing the new tower, check the upper shock mount holes for correct alignment and inspect associated posts and screws for movement. Use thread-lock in locations your manual recommends and re-establish camber and toe settings before normal running.

This direct-fit shock tower is a practical spare for the specified Savage models and suits repair tasks or suspension fine-tuning on those scale trucks.
