HB TCXX Precision Upper Deck 2.0mm by Arrowmax AM-TCXX-68484  [AM-TCXX-68484]

Precision 2.0mm top plate for HB TCXX

This component is an RC replacement upper deck intended for HB TCXX series cars, supplied as Arrowmax AM-TCXX-68484. With a 2.0mm section thickness it links the front and rear assemblies and helps control chassis twist while offering a repeatable mounting plane for servos, receivers and suspension pick-ups. The design emphasises correct fit and repeatability rather than advertised performance gains.

Fitting steps: remove the factory deck, position the AM-TCXX-68484 so the screw holes line up, and use the original screws to secure it. No special modifications are required on a standard HB TCXX chassis. After installation, inspect screw torque and ensure wiring and radio components clear the plate.

Setup advice: changing to a different deck thickness alters torsional stiffness. The 2.0mm option typically gives a neutral mid-range feel suitable for general track use; use it as part of a wider setup routine rather than as a stand-alone fix for handling issues.

Choose this 2.0mm replacement deck for consistent mounting and predictable stiffness on HB TCXX cars; verify fitment and check hardware after initial running.
