HB TCXX Main Chassis 2.5mm by Arrowmax AM-TCXX-68296  [AM-TCXX-68296]

HB TCXX Main Chassis 2.5mm

This Arrowmax product is an aftermarket main chassis plate produced for HB TCXX scale racing models, supplied under the code AM-TCXX-68296. It is described in the source only by its role and the 2.5mm plate thickness; no additional material or dimensional data is provided in the source. The item is intended for RC-scale on-road use only.

The chassis functions as the central structural plate for the HB TCXX platform, serving as the mount for suspension towers, drivetrain bearings, and electronics trays on compatible TCXX assemblies. In practice, a 2.5mm plate is a tuning choice that changes overall torsional stiffness compared with thinner plates, and installers will use it when they need a firmer baseline for setup adjustments.

Installation notes: this part is a direct replacement style component for HB TCXX-compatible layouts according to the product name and category path, so it uses the chassis' existing mounting pattern and fastener locations. Because the manufacturer did not publish fastener sizes or torque values in the source, follow your chassis manual for correct hardware and assembly sequence when swapping the plate.

Use this chassis plate as a like-for-like structural replacement on HB TCXX models when a 2.5mm baseline stiffness is required for tuning; confirm fit against your vehicle's parts list before installation.
