HB MAIN CHASSIS (2.5mm) TCXX**

This Arrowmax aftermarket main chassis plate is specified for HB TCXX scale racing cars and carries the model code AM-TCXX-68296. The source entry records only its role and the 2.5mm nominal thickness; it does not include extra dimensional or material data. The component is intended solely for on-road RC use.

The chassis plate is the central structural element on HB TCXX vehicles, acting as the mounting base for suspension towers, drivetrain bearings and electronics trays on compatible TCXX configurations. Using a 2.5mm plate alters torsional stiffness compared with thinner plates, and is typically selected when a stiffer tuning baseline is required.

Installation notes: the part is a direct-replacement style component for HB TCXX-compatible setups and will use the chassis existing mounting pattern and fastener locations. As the manufacturer did not publish fastener sizes or torque values in the source, consult your chassis manual for the correct hardware and assembly sequence when replacing the plate.
