Technical brief for the shock tower

This single-piece shock tower is designed to fit HPI Savage 21, Savage 25 and Savage X chassis as a direct replacement. It reinstates the upper shock mount points and provides a stable reference for suspension geometry and tuning.

Installation follows standard procedures for chassis maintenance: remove bodywork and any interfering upper links, unfasten the existing tower, transfer retained hardware and fasten the replacement. The tower is a structural mounting point and its correctness affects shock cant and upper link alignment rather than electrical or drivetrain systems.

After installation, verify the alignment of upper shock mount holes, check for play at the posts and fasteners, and use thread-lock where the chassis manual specifies. Re-establish camber and toe settings and perform a short test run to validate the geometry has not shifted.

Specifications

  • Item: Shock tower, 1 pcs
  • Material: Not specified by manufacturer
  • Model Number: HSA-007
  • Compatibility: HPI Savage 21, Savage 25, Savage X

Intended as a direct-fit upgrade for the listed Savage models, this tower helps maintain consistent upper mount geometry and supports precise suspension tuning and repairs.

What checks ensure correct fitment?

Confirm the hole spacing and orientation match the original tower, inspect post interfaces for wear, and ensure mounting hardware seats flush without distortion.

Any special preparation before installing?

Clean mounting surfaces, remove old thread-lock residue, and verify that replacement screws and posts are free of burrs to prevent misalignment.

How does this influence suspension setup?

The tower defines upper shock anchor points which influence shock angle and roll centre. After fitting, recheck shock geometry and adjust spring or damping settings if required.

What should I monitor during initial runs?

Listen for unusual noises, check for fastener loosening, and inspect mount posts for any signs of movement after a short test run to validate durability and fit.
