HB TCXX Rear Shock Tower Low Mount Upgrade - Arrowmax AM-TCXX-68764  [AM-TCXX-68764]

Rear low-mount shock bracket for HB TCXX

The Arrowmax AM-TCXX-68764 rear shock tower is an aftermarket component designed for the HB TCXX. With a low-mount design the top of the rear shocks sits lower on the chassis, altering the shock angle and mounting geometry relative to the standard tower.

Fitment follows the HB TCXX factory points and the tower uses existing shock studs and mounting hardware from the stock part. After installation check shock travel, ride height and clearance, and ensure the upper ball stud lines up before final tightening. This part is intended as a direct-fit upgrade for modellers who want a compact rear shock layout without changing other suspension pick-ups.

In tuning terms the low-mount arrangement reduces initial leverage and shifts roll centre, which can change rear grip, responsiveness to inputs and body attitude under throttle or braking. Use paired adjustments to spring rates and shock oil to refine balance; make incremental changes to isolate the tower's effect during track testing.
