HB TCXX Front Shock Tower Let Down - Tunable Upgrade Arrowmax AM-TCXX-68763-V2  [AM-TCXX-68763-V2]

TCXX front tower upgrade

This aftermarket front shock tower is made for the HB TCXX platform and supplied by Arrowmax under model AM-TCXX-68763-V2. The Let Down layout moves the shock mounting point lower on the tower to change leverage and roll behaviour while leaving existing shock units unchanged.

Fitment and role: built to replace the factory front tower on HB TCXX-compatible assemblies, this part modifies shock angle and front-end response as part of setup work for track or club racing. It functions solely as an aftermarket suspension piece and installs in the same mounting locations as the original TCXX tower.

Installation notes: remove the original tower, transfer any spacers, bushings, and fasteners that fit, then fit the Arrowmax replacement into the stock mount points. After installation verify ride height and piston positions, then run incremental setup tests to confirm the expected geometry changes.
