HB TCXX Top Deck 2.25mm Upgrade - Arrowmax AM-TCXX-68761-V2  [AM-TCXX-68761-V2]

2.25mm Top Deck Upgrade for HB TCXX by Arrowmax

The Arrowmax AM-TCXX-68761-V2 top deck is a 2.25mm aftermarket plate engineered for HB TCXX chassis. As a direct replacement for the stock upper plate, it alters chassis rigidity and handling feel while leaving suspension geometry unchanged.

Fit and installation: this upper deck is designed to align with the TCXX factory mounting points and to be secured using the existing screws and hardware. When fitting the part, check hole alignment and ensure screw lengths do not press into the ESC or battery strap.

Tuning role: a thicker 2.25mm deck decreases torsional flex compared with thinner plates, often giving more precise steering and less chassis roll during cornering. Fit this plate when you want a firmer front-to-rear response and balance it against spring and anti-roll bar adjustments one step at a time.

The AM-TCXX-68761-V2 offers a simple route to stiffer chassis behaviour on HB TCXX cars; always confirm fitment and adjust other setup pieces incrementally to find the best balance.
