HB TCXX 2.25mm Main Chassis by Arrowmax AM-TCXX-68483-V2  [AM-TCXX-68483-V2]

HB TCXX Main Chassis Overview

The Arrowmax AM-TCXX-68483-V2 is an aftermarket main chassis plate produced for the HB TCXX platform, specified at 2.25mm thickness and offered as a direct replacement option for standard TCXX kits. This RC-scale accessory is intended to alter chassis stiffness and balance when performing setup changes on 1/10 electric touring cars.

Use this chassis as a straightforward tuning item: swapping the plate can affect flex characteristics, understeer/oversteer tendencies, and how the suspension responds over varying track surfaces. Installation typically follows the original TCXX chassis mounting points, so basic disassembly of the stock plate and reuse of existing hardware is expected where applicable.

For racers and tuners using the HB TCXX platform, this V2 chassis plate provides a revision option for fine-tuning chassis flex and setup response without changing other major components; confirm fitment with your kit before installation.
