HB TCXX Upper Deck 2.5mm by Arrowmax AM-TCXX-68761  [AM-TCXX-68761]

Upper deck for HB TCXX

This upper deck is an aftermarket replacement part produced by Arrowmax for the HB TCXX platform, supplied under model AM-TCXX-68761. As a 2.5mm upper deck it is positioned to influence chassis stiffness and support the car's top-plate geometry, serving as a tuning item rather than an electrical or driveline component.

Use this part when you need a direct top-plate option for setup changes on Hot Bodies TCXX chassis. During installation, verify clearances around the servo, ESC leads, and shock towers, and retorque all mounting hardware after the first run. The deck's thickness is intended to alter flex characteristics relative to thinner stock pieces, so expect measurable changes in handling and weight distribution when swapped.

A focused tuning part for HB TCXX setups, useful for track-side adjustments and chassis stiffness testing.
