HB TCXX Let-Down Rear Shock Tower - Arrowmax AM-TCXX-68764-V2  [AM-TCXX-68764-V2]

Rear shock tower summary

This Arrowmax AM-TCXX-68764-V2 rear shock tower is an aftermarket let-down mount made for the HB TCXX chassis, designed to lower the rear shock eye and alter attachment geometry. It gives a defined mounting location to change shock angle and leverage, letting tuners refine initial compression and rear roll without replacing other suspension links.

Provided as a direct-fit for HB TCXX cars, this tower is used to modify rear roll behaviour and test different shock angles during chassis setup. Competent drivers usually compare handling before and after fitment to judge changes in traction and transient response.

Installation guidance focuses on fit and outcome rather than step-by-step instructions: ensure the tower aligns with HB TCXX shock tower holes and ball studs, keep mounting faces clean, and check that shock travel remains unobstructed after fitting. Combine changes from this tower with spring rate, damper tuning and sway bar adjustments to dial in rear grip.
